Abstract

Background

Fatigue is a common and debilitating symptom in people receiving dialysis that is associated with an increased risk of death, cardiovascular disease and depression. Fatigue can also impair quality of life (QoL) and the ability to participate in daily activities. Fatigue has been established by patients, caregivers and health professionals as a core outcome for haemodialysis (HD).

Objectives

We aimed to evaluate the effects of pharmacological and non‐pharmacological interventions on fatigue in people with kidney failure receiving dialysis, including HD and peritoneal dialysis (PD), including any setting and frequency of the dialysis treatment.

Search methods

We searched the Cochrane Kidney and Transplant Register of Studies up to 18 October 2022 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Registry Platform (ICTRP) Search Portal and ClinicalTrials.gov.

Selection criteria

Studies evaluating pharmacological and non‐pharmacological interventions affecting levels of fatigue or fatigue‐related outcomes in people receiving dialysis were included. Studies were eligible if fatigue or fatigue‐related outcomes were reported as a primary or secondary outcome. Any mode, frequency, prescription, and duration of therapy were considered.

Data collection and analysis

Three authors independently extracted data and assessed the risk of bias. Treatment estimates were summarised using random effects meta‐analysis and expressed as a risk ratio (RR) or mean difference (MD), with a corresponding 95% confidence interval (CI) or standardised MD (SMD) if different scales were used. Confidence in the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

Main results

Ninety‐four studies involving 8191 randomised participants were eligible. Pharmacological and non‐pharmacological interventions were compared either to placebo or control, or to another pharmacological or non‐pharmacological intervention. In the majority of domains, risks of bias in the included studies were unclear or high.

In low certainty evidence, when compared to control, exercise may improve fatigue (4 studies, 217 participants (Iowa Fatigue Scale, Modified Fatigue Impact Scale, Piper Fatigue Scale (PFS), or Haemodialysis‐Related Fatigue scale score): SMD ‐1.18, 95% CI ‐2.04 to ‐0.31; I2 = 87%) in HD.

In low certainty evidence, when compared to placebo or standard care, aromatherapy may improve fatigue (7 studies, 542 participants (Fatigue Severity Scale (FSS), Rhoten Fatigue Scale (RFS), PFS or Brief Fatigue Inventory score): SMD ‐1.23, 95% CI ‐1.96 to ‐0.50; I2 = 93%) in HD.

In low certainty evidence, when compared to no intervention, massage may improve fatigue (7 studies, 657 participants (FSS, RFS, PFS or Visual Analogue Scale (VAS) score): SMD ‐1.06, 95% CI ‐1.47, ‐0.65; I2 = 81%) and increase energy (2 studies, 152 participants (VAS score): MD 4.87, 95% CI 1.69 to 8.06, I2 = 59%) in HD.

In low certainty evidence, when compared to placebo or control, acupressure may reduce fatigue (6 studies, 459 participants (PFS score, revised PFS, or Fatigue Index): SMD ‐0.64, 95% CI ‐1.03 to ‐0.25; I2 = 75%) in HD.

A wide range of heterogenous interventions and fatigue‐related outcomes were reported for exercise, aromatherapy, massage and acupressure, preventing our capability to pool and analyse the data.

Due to the paucity of studies, the effects of pharmacological and other non‐pharmacological interventions on fatigue or fatigue‐related outcomes, including non‐physiological neutral amino acid, relaxation with or without music therapy, meditation, exercise with nandrolone, nutritional supplementation, cognitive‐behavioural therapy, ESAs, frequent HD sections, home blood pressure monitoring, blood flow rate reduction, serotonin reuptake inhibitor, beta‐blockers, anabolic steroids, glucose‐enriched dialysate, or light therapy, were very uncertain.

The effects of pharmacological and non‐pharmacological treatments on death, cardiovascular diseases, vascular access, QoL, depression, anxiety, hypertension or diabetes were sparse. No studies assessed tiredness, exhaustion or asthenia. Adverse events were rarely and inconsistently reported.

Authors' conclusions

Exercise, aromatherapy, massage and acupressure may improve fatigue compared to placebo, standard care or no intervention. Pharmacological and other non‐pharmacological interventions had uncertain effects on fatigue or fatigue‐related outcomes in people receiving dialysis. Future adequately powered, high‐quality studies are likely to change the estimated effects of interventions for fatigue and fatigue‐related outcomes in people receiving dialysis.

Plain language summary

Are interventions for fatigue effective among people with kidney failure requiring dialysis?

What is the issue?

Fatigue is a frequent and debilitating symptom that can limit life participation in people receiving dialysis. Fatigue is linked to impaired quality of life, cardiovascular disease, death and depression in people on dialysis. Several potential interventions, including drugs or other non‐pharmacological treatments (e.g. exercise, diet, massage, aromatherapy, acupressure), have been evaluated for their effect on fatigue in people on dialysis.

What did we do?

We evaluated whether drugs or other non‐pharmacological interventions are beneficial for adults and children receiving haemodialysis or peritoneal dialysis to manage fatigue. We evaluated all clinical studies available and summarised the results. We evaluated how certain we could be about the evidence related to interventions for fatigue using a system called "GRADE".

What did we find?

Ninety‐four studies involving 8191 randomised participants were available. Patients in the studies were given a drug, non‐pharmacological intervention, standard care or a sugar pill (placebo). The treatment they received was decided by random chance. The studies were generally short‐term (over a few months). There were no studies in children. Exercise, aromatherapy, massage and acupressure improve fatigue compared to placebo or standard care. Drugs or other non‐pharmacological interventions have uncertain effects on fatigue in people on dialysis.

Conclusions

Exercise, aromatherapy, massage and acupressure improve fatigue compared to placebo or standard care. It remains uncertain whether drugs or other non‐pharmacological interventions have any impact on fatigue in people on dialysis when compared to a sugar pill, standard care or other treatments for fatigue.

Background

Description of the condition

Fatigue is common in people on dialysis, and it is associated with an increased risk of death, cardiovascular disease (CVD), depression and impaired quality of life (QoL) (Chiaranai 2016; Evangelidis 2017; Jhamb 2008; Ju 2021; Manera 2019). The prevalence of fatigue is estimated to range from 42% to 89% in adult patients on haemodialysis (HD) and peritoneal dialysis (PD) (Chang 2001; Jhamb 2008; Maruyama 2021; Picariello 2017a; Yngman‐Uhlin 2010).

Fatigue is defined as a continuum sense of tiredness or exhaustion that can prevent patients from being able to do their usual activities (Jhamb 2008; Ju 2018b; Lee 1991).

The causes of fatigue are complex and multifactorial and may be related to uremia, anaemia, inflammation, fluid shifts and metabolic processes (Ju 2018a). For patients receiving HD, physiological factors, such as anaemia, have been shown to be associated with fatigue, and studies suggest that the use of erythropoietin stimulating agents (ESAs) to treat anaemia improves QoL, fatigue and energy levels in patients on HD (Johansen 2012; Ross 2003). Cytokines may contribute to fatigue in people on HD as elevated levels of pro‐inflammatory cytokines are seen in kidney failure requiring kidney replacement therapy (KRT) (Artom 2014; Bergstrom 2000; Rao 2007; van Sandwijk 2019). Treatment‐related factors such as dialysis frequency or modality have also been shown to affect fatigue (Jhamb 2008; Picariello 2017a). Post‐dialysis fatigue is an intense fatigue experienced by patients after an HD session (Bossola 2020). Patients who received daily HD have reported less post‐dialysis fatigue than those who had more days off between dialysis sessions, suggesting that this symptom may be related to treatment frequency. Modalities, such as nocturnal dialysis, may help patients recover from post‐dialysis fatigue faster (Liangos 2010). Psychosocial and lifestyle factors correlated with fatigue in HD include depression, physical inactivity, and poor sleep quality (Jhamb 2008; Maruyama 2021).

In the PD population, clinical factors associated with fatigue scores include cholesterol, weekly creatinine clearance, transferrin, alkaline phosphatase, and serum intact parathyroid hormone (Chang 2001; Tian 2020).

Fatigue can be extremely debilitating (Chiaranai 2016; Debnath 2021; Horigan 2013; Yngman‐Uhlin 2010), and patients experience a limitation in freedom, a loss of sense of self and social connectedness (Davey 2019; Monaro 2014). Fatigue has recently been established by patients and health professionals as a core outcome to be reported in all trials in people receiving HD (Evangelidis 2017; Tong 2017).

Description of the intervention

As the causes of fatigue are uncertain and likely to be multifactorial, a range of pharmacological (including ESAs), novel anaemia therapies or levocarnitine) and non‐pharmacological interventions (such as diet, massage, aromatherapy, meditation, cognitive behavioural therapy (CBT) or frequency of dialysis treatments) were considered.

How the intervention might work

Both pharmacological and non‐pharmacological interventions may improve fatigue. For example, ESAs or other interventions to achieve higher haemoglobin (Hb) targets and levocarnitine to modify the effects of defective fatty‐acid metabolism have been shown to improve symptoms of fatigue (Foley 2009; Johansen 2012; Ossareh 2003; Schreiber 2005). Recently, hypoxia‐inducible factors (HIF), a new class of drugs to treat anaemia, might be effective in the treatment of fatigue, but data are still sparse (Chertow 2021). Non‐pharmacological interventions that focus on psychosocial and lifestyle aspects, including diet, exercise, sleep, foot reflexology, aromatherapy and yoga, may also help to improve fatigue (Eglence 2013; Habibzadeh 2020; Karadag 2019; Salehi 2020; Yurtkuran 2007). Physical activity may improve fatigue through indirect effects on cytokine levels or by increasing muscle strength (Jhamb 2008). CBT has also demonstrated improvement in sleep and fatigue in this population (Chen 2008; Chen 2011a; Unruh 2020). Frequent and longer dialysis treatment may reduce post‐dialysis fatigue and improve general well‐being (Bossola 2020). However, the exact causal mechanism of improvements seen in these studies remains unknown.

Why it is important to do this review

It is widely known that fatigue is one of the most common and debilitating symptoms experienced by people on dialysis. In the HD population, fatigue has been consistently identified as the most critically important outcome and a high research priority in people on HD (Evangelidis 2017; Ju 2018a; Urquhart‐Secord 2016). The last decade has seen a growing number of studies on pharmacological and lifestyle interventions to improve fatigue. There have been systematic reviews focusing on one particular type of pharmacological intervention, such as levocarnitine (Schreiber 2005) or ESAs (Johansen 2012). Few systematic reviews have been published on non‐pharmacological interventions for fatigue (Astroth 2013; Bouya 2018; Melo 2020; Song 2018). Furthermore, it is unclear how the efficacy of these interventions compares to pharmacological interventions.

In this review, we summarised and synthesised all current evidence of the benefits and harms of interventions that have been evaluated for their impact on fatigue in people on dialysis. The definition of fatigue and fatigue‐related outcomes were reported according to the definition provided by the authors. We considered all pharmacological and non‐pharmacological interventions as the potential causes of fatigue are diverse and likely to be multifactorial. In doing so, this review may shed light on any existing evidence for an intervention that effectively reduces or manages fatigue. Information on the efficacy of different interventions and other factors that facilitate or challenge the improvement of fatigue will allow clinicians to provide effective care for their patients' experience of this debilitating symptom. Furthermore, as fatigue is associated with other outcomes such as death, cardiovascular diseases and broader QoL, improvement in this symptom may translate into better patient outcomes overall.

Objectives

We aimed to evaluate the effects of any pharmacological and non‐pharmacological interventions on fatigue in people with kidney failure requiring dialysis, such as HD and PD, including any setting (e.g. dialysis performed in the clinic or at home) and frequency.

Methods

Criteria for considering studies for this review

Types of studies

All randomised controlled trials (RCTs) and quasi‐RCTs (RCTs in which allocation to treatment was obtained by alternation, use of alternate medical records, date of birth, or other predictable methods) of interventions whereby fatigue or fatigue‐related outcomes were reported as either primary or secondary outcome.

Types of participants

Inclusion criteria

Patients of any age with kidney failure on any form of dialysis. The dialysis treatment could be performed both in the clinic and at home. Any frequency of the dialysis treatment was included.

Exclusion criteria

None.

Types of interventions

We considered any intervention affecting levels of self‐reported fatigue in patients on dialysis. Studies were included if fatigue was reported as an outcome.

  • Pharmacological treatment (including but not limited to): psychostimulants (amphetamines, modafinil, armodafinil, methylphenidate, pemoline), amantadine, corticosteroids (dexamethasone, prednisone, methylprednisolone), donepezil, antidepressants (selective serotonin reuptake inhibitors, paroxetine), anxiolytics, ESAs, HIF, human growth hormone, tumour necrosis factor (TNF) inhibitor, acetylsalicylic acid, megestrol acetate, alfacalcidol and intravenous (IV) levocarnitine

  • Non‐pharmacological treatment (including but not limited to): nutrition (albumin, diet), therapeutic exercise (e.g. inspiratory muscle training exercise, aerobic exercise), alternative and complementary medicine (acupressure, Chinese herbal medicine and acupuncture), psychosocial (psychotherapy, psycho‐education such as cognitive restructuring, coping strategies, stress management), educational (goal‐setting, providing information/advice on symptom management/nutrition).

Any mode, frequency, prescription, and duration of therapy were considered. The intervention may be administered at any time or day (i.e. dialysis or non‐dialysis days) and in clinical or non‐clinical settings.

Types of outcome measures

We used time points of measurements as reported by investigators, as well as assessing the outcome measures at the end of the treatment.

Primary outcomes

Fatigue and fatigue‐related outcomes such as tiredness, exhaustion, weakness, energy/vitality and asthenia that have been assessed through any self‐report measure (open‐ended questionnaires such as fatigue diary, fatigue‐specific scales (e.g. Functional Assessment of Chronic Illness Therapy Fatigue subscale (FACIT‐F), Chalder Fatigue Scale (CFS)), or fatigue sub‐scale as part of a measure assessing a broader construct (e.g. Short Form‐36 (SF‐36), or visual analogue scale (VAS)). We considered all patient‐reported outcome measures for fatigue, given the lack of validation work conducted in the dialysis population. To avoid misinterpretation of the data, definitions of fatigue and fatigue‐related outcomes were reported according to the definitions provided by the authors. Fatigue and fatigue‐related outcomes (including tiredness, exhaustion, weakness, energy/vitality and asthenia) were assessed separately.

Secondary outcomes

QoL, depression, anxiety, death (any cause and cardiovascular), vascular access, CVD, hypertension, diabetes, sleep and mood.

Data collection and analysis

Selection of studies

The search strategy described was used to obtain titles and abstracts of studies that may be relevant to the review. The titles and abstracts were screened independently by three authors (PN, AJ, VS). Three authors (PN, AJ, VS) independently assessed retrieved abstracts and, if necessary, the full text of these studies to determine which studies satisfy the inclusion criteria.

Data extraction and management

Data relating to study design (RCT, quasi‐RCT), participant characteristics (e.g. age, gender, dialysis vintage, comorbidity), interventions (pharmacological, non‐pharmacological) and outcomes (as described above) were extracted. Three authors (PN, AJ, VS) independently carried out data extraction using a standard data extraction form. Studies reported in non‐English languages were translated before assessment. Where more than one publication of a study exists, the publications were grouped together, and the report with the most complete data was included in the meta‐analyses. Where relevant outcomes are only published in earlier versions, these data were used. Any discrepancies between published versions were highlighted. Any further information required from the original author was requested by written correspondence, and any relevant information obtained in this manner was included in the review. Disagreements were resolved by consensus in consultation with another author (AJ).

Assessment of risk of bias in included studies

The following items were independently assessed by two authors (PN, VS) using the risk of bias assessment tool (Higgins 2022) (see Appendix 2).

  • Was there adequate sequence generation (selection bias)?

  • Was allocation adequately concealed (selection bias)?

  • Was knowledge of the allocated interventions adequately prevented during the study?

    • Participants and personnel (performance bias)

    • Outcome assessors (detection bias)

  • Were incomplete outcome data adequately addressed (attrition bias)?

  • Are reports of the study free of suggestion of selective outcome reporting (reporting bias)?

  • Was the study apparently free of other problems that could put it at risk of bias?

Measures of treatment effect

For dichotomous outcomes (e.g. adverse events, cardiovascular events, death), results were expressed as risk ratio (RR) with 95% confidence intervals (CI). Where continuous scales of measurement are used to assess the effects of treatment (e.g. depression, fatigue), the mean difference (MD) was used, or the standardised mean difference (SMD) if different scales were used.

Unit of analysis issues

Cluster‐randomised studies

We anticipated that studies using clustered randomisation had controlled for clustering effects. In case of doubt, we contacted the first authors to ask for individual participant data to calculate an estimate of the intracluster correlation coefficient (ICC). If this was not possible, we obtained external estimates of the ICC from a similar study or from a study of a similar population as described in the Cochrane Handbook for Systematic Reviews of Interventions (Higgins 2022). When the ICC was established, we used it to re‐analyse the study data. If ICCs from other sources were used, we reported this and conducted sensitivity analyses to investigate the effect of variations in the ICC.

Cross‐over studies

We included all randomised cross‐over studies in the systematic review if they report a paired (comparison within the patient) analysis using all periods. If not, we only used the data from the first period.

Studies with more than two treatment arms

If more than one of the interventions is a fatigue intervention, and there is sufficient information in the study to assess the similarity of the interventions, we combined similar interventions to allow for a single pair‐wise comparison.

Dealing with missing data

Any further information required from the original author was requested by written correspondence (e.g. emailing the corresponding author), and any relevant information obtained in this manner was included in the review. Evaluation of important numerical data such as screened, randomised patients as well as intention‐to‐treat, as‐treated and per‐protocol population were carefully performed. Attrition rates, for example, drop‐outs, losses to follow‐up and withdrawals, were investigated. Issues of missing data and imputation methods (for example, last‐observation‐carried‐forward) were critically appraised (Higgins 2022).

Assessment of heterogeneity

We first assessed the heterogeneity by visual inspection of the forest plot. We quantified statistical heterogeneity using the I2 statistic, which describes the percentage of total variation across studies that is due to heterogeneity rather than sampling error (Higgins 2003). A guide to the interpretation of I2 values was as follows:

  • 0% to 40%: might not be important

  • 30% to 60%: may represent moderate heterogeneity

  • 50% to 90%: may represent substantial heterogeneity

  • 75% to 100%: considerable heterogeneity.

The importance of the observed value of I2 depends on the magnitude and direction of treatment effects and the strength of evidence for heterogeneity (e.g. P value from the Chi2 test or a CI for I2) (Higgins 2022).

Assessment of reporting biases

If possible, funnel plots were used to assess for the potential existence of small study bias (Higgins 2022). There were insufficient studies per comparision to do this.

Data synthesis

Data were pooled using the random‐effects model but the fixed‐effect model was also used to ensure robustness of the model chosen and susceptibility to outliers.

Subgroup analysis and investigation of heterogeneity

We reported the results of our findings separately, focusing on fatigue, as reported by the authors. Adverse effects were tabulated and assessed with descriptive techniques, as they were likely to be different for the various interventions used. Where possible, the risk differences with 95% CI were calculated for each adverse effect, either compared to no treatment or to another agent.

Based on available data, we planned to perform the following subgroup analyses.

  • Age: < 18 years versus ≥ 18 years; and < 64 years versus ≥ 64 years

  • Gender: female versus male

  • Risk of bias: high versus low (versus unclear) (allocation concealment, blinding of outcome assessors, incomplete outcome data)

  • Indication: studies targeting fatigue versus reporting fatigue

  • Intervention type: pharmacological versus non‐pharmacological

  • Presence of comorbidities: CVD (yes versus no), diabetes (yes versus no), hypertension (yes versus no), depression (clinical diagnosis versus none)

  • Fatigue outcome measures used: validation data available versus de novo

  • Dialysis type: PD versus HD

  • Dialysis vintage: < 5 years versus ≥ 5 years

Sensitivity analysis

We planned to perform sensitivity analyses in order to explore the influence of the following factors on effect size:

  • Repeating the analysis excluding abstract‐only publication

  • Repeating the analysis excluding industry‐funded studies

  • Repeating the analysis, taking account of the risk of bias (allocation concealment)

  • Repeating the analysis, excluding any very long or large studies, to establish how much they dominate the results.

Summary of findings and assessment of the certainty of the evidence

We presented the main results of the review in 'Summary of findings' tables. These tables presented key information concerning the quality of the evidence, the magnitude of the effects of the interventions examined, and the sum of the available data for the main outcomes (Schünemann 2022a). The 'Summary of findings' tables also included an overall grading of the evidence related to each of the main outcomes using the GRADE (Grades of Recommendation, Assessment, Development and Evaluation) approach (GRADE 2008; GRADE 2011). The GRADE approach defines the quality of a body of evidence as the extent to which one can be confident that an estimate of effect or association is close to the true quantity of specific interest. The quality of a body of evidence involves consideration of within‐trial risk of bias (methodological quality), directness of evidence, heterogeneity, precision of effect estimates and risk of publication bias (Schünemann 2022b). We presented the following outcomes in the 'Summary of findings' tables:

  • Fatigue

  • Weakness

  • Energy

  • Tiredness

  • Exhaustion

  • Asthenia

Included studies

The Characteristics of included studies tables reported the characteristics of the participants and the interventions in the included studies. A total of 94 studies (8191 randomised participants) were included in this review.

Study design, setting and characteristics

Four studies had a quasi‐randomised design, two studies had a cluster‐randomisation design, 13 studies had a cross‐over design, and the remaining studies were RCTs. Studies were conducted from 1979 to 2022 in Australia (two studies), Brazil (three studies), Canada (seven studies), China (one study), Denmark (one study), Egypt (two studies), Germany (one study), Greece (four studies), Hong Kong (one study), India (two studies), Iran (22 studies), Italy (one study), Japan (four studies), Switzerland (one study), Taiwan (11 studies), Turkey (nine studies), the UK (three studies), the USA (15 studies), were performed in multinational setting (two studies) or did not report information about the country (two studies). Study follow‐up ranged from one week (four studies) to 21.8 months (one study), with a median of 1.8 months. Fourteen studies received funding from pharmaceutical companies. Six studies were available only as conference abstracts.

Study participants

Three studies were conducted in people with PD, five studies in people with both HD and PD, one study was performed in people with either HD or haemodiafiltration (HDF), one study did not specify the type of dialysis, whilst all other studies were performed in people receiving HD. The mean dialysis vintage ranged from 0.3 to 12.7 years, with a median of 4.1 years. The sample size varied from five to 596 participants, with a median of 61 participants. The mean study age ranged from 38 years to 69 years, with a median of 56 years. No studies evaluated treatment in children.

Thirteen studies included people with and without cardiovascular comorbidities at baseline; one study excluded people with CVD, while one study included only patients with previous CVD. Forty‐seven studies included people with and without diabetes. Of these studies, only one study reported subgroup analyses for people with and without diabetes. Two studies did not include people with diabetes, while one study was performed in people with diabetes. Thirty‐three studies were performed in people with and without hypertension; one study did not include people with hypertension, while one study was focused only on people with hypertension. Clinical diagnosis of depression was rarely reported: two studies excluded people with depression, two studies included only people with depression at baseline, and one study included people with and without depression.

The definition of fatigue and fatigue‐related outcomes were reported according to the definition provided by the authors. Fatigue was assessed using different tools (see Appendix 3).

Seven studies reported fatigue only as an adverse event.

Allocation

Random sequence generation

Forty‐one studies were judged to be low risk for adequately providing methods used for random sequence generation. Fifty‐one studies were judged to be unclear risk as they stated to be randomised but provided no further details on how this was undertaken. Two studies were judged to be high risk.

Allocation concealment

Allocation concealment was assessed as adequate in 18 studies, high risk in three studies, and unclear risk in 73 studies.

Blinding

Performance bias

Eight studies were blinded and considered to be at low risk of bias for performance bias, and 73 studies were not blinded and were considered at high risk of performance bias. Thirteen studies were assessed as unclear risk of bias.

Detection bias

Blinding of outcome assessment was judged to be at low risk in seven studies, and 87 studies were considered at high risk of detection bias.

Incomplete outcome data

Data follow‐up was complete in 13 studies, incomplete in 63 studies, whilst 18 studies were assessed as unclear risk of bias.

Selective reporting

Eight studies reported expected and clinically‐relevant outcomes and were deemed to be at low risk of bias, and 86 studies did not report key patient‐centred outcomes, including fatigue, cardiovascular disease, death and vascular access.

Other potential sources of bias

Forty‐five studies appeared to be free from other sources of bias, 15 studies reported other sources of bias (including the role of funding source and/or imbalance in baseline treatment groups). It was unclear risk whether 34 studies had other sources of bias.

Discussion

Summary of main results

We identified 94 studies (8191 randomised participants) evaluating interventions for fatigue in people with CKD requiring dialysis, including people receiving HD or PD. No studies were carried out in children. Risks of bias in the included studies were often unclear or high, leading to GRADE rated at low or very low certainty evidence.

Exercise, aromatherapy, massage and acupressure may improve fatigue compared to placebo, standard care or no intervention. A wide range of heterogenous interventions and fatigue‐related outcomes were reported for exercise, aromatherapy, massage and acupressure, preventing us from pooling and analysing the data.

Due to the paucity of studies, the effects of other pharmacological and other non‐pharmacological interventions on fatigue, including non‐physiological neutral amino acids, relaxation with or without music therapy, exercise with nandrolone, nutritional supplementation, CBT, ESAs, frequent HD sections, home BP monitoring, blood flow rate reduction, serotonin reuptake inhibitor, beta‐blockers, anabolic steroids, glucose‐enriched dialysate, or light therapy, were very uncertain.

The effects of pharmacological and non‐pharmacological treatments on death, cardiovascular diseases, vascular access, QoL, depression, anxiety, hypertension or diabetes were sparse. No studies assessed tiredness, exhaustion or asthenia. Adverse events were rarely and inconsistently reported. Meta‐analysis was not possible for the majority of the outcomes for these compared treatments due to single studies available for clinical outcomes.

Overall completeness and applicability of evidence

In this review, we identified 94 studies comparing a broad range of interventions for fatigue in people receiving dialysis. Currently, evidence from existing studies is of low or very low certainty and is therefore not available to inform clinical care or policy. The majority of the included studies were performed in people on HD. No studies were conducted in children.

Most studies compared an intervention for fatigue with a placebo or control, and clinically important outcome data were rarely reported. A description of the interventions has been reported in Appendix 4. The majority of studies had a small sample size with a short duration, had methodological limitations, cross‐over or quasi‐RCT design, or were primarily designed to evaluate surrogate measures of effect. No outcome data were available for tiredness, exhaustion, or asthenia. Adverse events related to treatment were not systematically reported (see Appendix 5).

Future studies on interventions for treating fatigue in people undergoing HD and PD should evaluate outcomes as prioritised by patients, caregivers and health professionals (SONG‐HD; SONG‐PD) to better inform clinical practice and decision‐making.

Quality of the evidence

We used the standard risk of bias domains within the Cochrane tool together with GRADE methodology (GRADE 2008) to assess the certainty of study evidence. Since the certainty of evidence was low or very low for all outcomes, future studies might provide different results.

Some studies were at high or unclear risks of bias for most of the risk of bias domains assessment. The majority of studies did not report adequate blinding, attrition or selective reporting, and some received some funding from pharmaceutical companies. Relevant clinical outcomes were rarely available for many of the included studies.

Fatigue has been measured using different tools, and a high heterogeneity in the fatigue‐related outcomes definition has been provided by authors, preventing our capability to pool the data. The variability in the reporting methods of some outcomes hamper data synthesis by meta‐analysis. The limited number of studies prevented the exploration of other potential sources of heterogeneity in the analyses. Subgroup and sensitivity analysis could not be done to explore heterogeneity owing to insufficient data. Due to the limited number of studies, the assessment of adverse events was not possible. All studies reported SD or SE as an estimate of variance, and some of them provided data in descriptive or figure format only.

Potential biases in the review process

This review was carried out using standard Cochrane methods. A highly sensitive search of the Cochrane Kidney Transplant specialised register was undertaken in October 2022, without language restriction and including grey literature. Each step was completed independently by at least two authors, including the selection of studies, data management, and risk of bias assessment to minimise the risks of misclassification and adjudication of evidence. Authors were contacted to collect further data as possible. Many studies did not report key outcomes in a format available for meta‐analysis.

Potential biases identified in our review included:

  1. The limited number of studies was a constraint on our ability to assess for potential reporting bias and selective outcome reporting

  2. Fatigue was assessed using a broad range of measures and definitions

  3. Poor quality studies could not be excluded due to the small number of included studies

  4. Heterogeneity between treatment interventions was precluded due to the small number of data observations

  5. The effects of interventions for fatigue on longer‐term outcomes were uncertain, and the treatment endpoints were principally surrogate outcomes (e.g. laboratory parameters)

  6. A large number of comparisons were identified that prevented pooling and meta‐analysis of the data. In addition, the definitions of both the intervention and control groups were quite heterogeneous among the included studies

  7. Some outcomes reported zero events, referred to a single study or both

  8. Adverse events were rarely and inconsistently reported

  9. Formal assessment for publication bias through visualisation of asymmetry in funnel plots could not be performed due to the limited number of studies available

Agreements and disagreements with other studies or reviews

We believe this is the first large and comprehensive review that included both pharmacological and non‐pharmacological interventions for fatigue in people receiving dialysis. However, some studies have examined the efficacy of either pharmacological or non‐pharmacological interventions for fatigue in this population, but the number of meta‐analyses published is still limited.

Astroth 2013 performed a systematic review of non‐pharmaceutical interventions for fatigue in adults receiving HD. The data showed that non‐pharmacological interventions (including infrared rays, exercise and acupressure) reduced fatigue in this setting. The main differences with our review included that Astroth 2013 excluded patients undergoing PD, children and non‐English papers.

Picariello 2017 carried out a systematic review and meta‐analysis to evaluate the efficacy of social‐psychological interventions for the management of fatigue in CKD. Sixteen RCTs (1536 participants) were included. Out of the 16 studies, only six reported social‐psychological interventions improved fatigue in this setting, and data were not meta‐analysed. However, they included adults with CKD stages 3‐5, including people requiring KRT (HD, PD and kidney transplant recipients).

Melo 2020 conducted a systematic review of the effects of acupressure in CKD on QoL, sleep and fatigue. Only three out of nine studies (270 participants) focused on fatigue, showing a positive effect of this intervention on fatigue. However, they evaluated RCTs, including any CKD stages and excluded studies classified with a level of evidence lower than three by the Jadad scores. GRADE assessment was not performed.

Song 2018 conducted a systematic review and meta‐analysis on the effects of exercise training compared to routine care in adult patients receiving HD. The treatment was not specifically provided for managing fatigue, but fatigue was reported as an outcome in three included studies (139 participants). Exercise training improved fatigue in HD. The main differences with our review were related to the inclusion and exclusion criteria, analyses were performed using a fixed model, and there was no information regarding the GRADE approach was provided.

Bouya 2018 performed a systematic review to assess the effect of aromatherapy on a broad range of complications of HD, including fatigue. Although the authors included 22 studies, only four addressed fatigue in this setting. Two out of four studies reported that lavender essence aromatherapy reduced fatigue in HD. Compared to our review, Bouya 2018 included both RCTs and observational studies and used the Jadad scale to assess the studies. GRADE assessment was not performed.

Johansen 2012 carried out a systematic review of the impact of ESAs on fatigue in adults receiving dialysis. This review included both RCTs and observational studies. Non‐English papers were excluded. Although ESAs showed improvement in fatigue, the main differences with our review were related to the inclusion and exclusion criteria, which prevented our ability to compare their findings with our data.

Authors' conclusions

Implications for practice.

Exercise, aromatherapy, massage and acupressure may improve fatigue compared to placebo, standard care or no intervention. Pharmacological and other non‐pharmacological interventions had uncertain effects on fatigue or fatigue‐related outcomes in people receiving dialysis. There is no evidence to inform decision‐making in children. Evidence is largely lacking in PD. Adverse events were rarely and inconsistently reported.

Implications for research.

Future well‐designed and adequately powered RCTs should be conducted to assess the benefits and harms of treatments to increase our confidence in the interventions for fatigue in people receiving HD or PD.

Further research is likely to change the estimated effects of interventions for fatigue and fatigue‐related outcomes in people receiving dialysis. Evaluation of cost‐effectiveness for interventions for fatigue would assist decision‐making by policy‐makers and health care providers in this setting.

Appendix 2. Risk of bias assessment tool

Potential source of bias Assessment criteria
Random sequence generation
Selection bias (biased allocation to interventions) due to inadequate generation of a randomised sequence
Low risk of bias: Random number table; computer random number generator; coin tossing; shuffling cards or envelopes; throwing dice; drawing of lots; minimisation (minimisation may be implemented without a random element, and this is considered to be equivalent to being random).
High risk of bias: Sequence generated by odd or even date of birth; date (or day) of admission; sequence generated by hospital or clinic record number; allocation by judgement of the clinician; by preference of the participant; based on the results of a laboratory test or a series of tests; by availability of the intervention.
Unclear: Insufficient information about the sequence generation process to permit judgement.
Allocation concealment
Selection bias (biased allocation to interventions) due to inadequate concealment of allocations prior to assignment
Low risk of bias: Randomisation method described that would not allow investigator/participant to know or influence intervention group before eligible participant entered in the study (e.g. central allocation, including telephone, web‐based, and pharmacy‐controlled, randomisation; sequentially numbered drug containers of identical appearance; sequentially numbered, opaque, sealed envelopes).
High risk of bias: Using an open random allocation schedule (e.g. a list of random numbers); assignment envelopes were used without appropriate safeguards (e.g. if envelopes were unsealed or non‐opaque or not sequentially numbered); alternation or rotation; date of birth; case record number; any other explicitly unconcealed procedure.
Unclear: Randomisation stated but no information on method used is available.
Blinding of participants and personnel
Performance bias due to knowledge of the allocated interventions by participants and personnel during the study
Low risk of bias: No blinding or incomplete blinding, but the review authors judge that the outcome is not likely to be influenced by lack of blinding; blinding of participants and key study personnel ensured, and unlikely that the blinding could have been broken.
High risk of bias: No blinding or incomplete blinding, and the outcome is likely to be influenced by lack of blinding; blinding of key study participants and personnel attempted, but likely that the blinding could have been broken, and the outcome is likely to be influenced by lack of blinding.
Unclear: Insufficient information to permit judgement
Blinding of outcome assessment
Detection bias due to knowledge of the allocated interventions by outcome assessors.
Low risk of bias: No blinding of outcome assessment, but the review authors judge that the outcome measurement is not likely to be influenced by lack of blinding; blinding of outcome assessment ensured, and unlikely that the blinding could have been broken.
High risk of bias: No blinding of outcome assessment, and the outcome measurement is likely to be influenced by lack of blinding; blinding of outcome assessment, but likely that the blinding could have been broken, and the outcome measurement is likely to be influenced by lack of blinding.
Unclear: Insufficient information to permit judgement
Incomplete outcome data
Attrition bias due to amount, nature or handling of incomplete outcome data.
Low risk of bias: No missing outcome data; reasons for missing outcome data unlikely to be related to true outcome (for survival data, censoring unlikely to be introducing bias); missing outcome data balanced in numbers across intervention groups, with similar reasons for missing data across groups; for dichotomous outcome data, the proportion of missing outcomes compared with observed event risk not enough to have a clinically relevant impact on the intervention effect estimate; for continuous outcome data, plausible effect size (difference in means or standardised difference in means) among missing outcomes not enough to have a clinically relevant impact on observed effect size; missing data have been imputed using appropriate methods.
High risk of bias: Reason for missing outcome data likely to be related to true outcome, with either imbalance in numbers or reasons for missing data across intervention groups; for dichotomous outcome data, the proportion of missing outcomes compared with observed event risk enough to induce clinically relevant bias in intervention effect estimate; for continuous outcome data, plausible effect size (difference in means or standardized difference in means) among missing outcomes enough to induce clinically relevant bias in observed effect size; ‘as‐treated’ analysis done with substantial departure of the intervention received from that assigned at randomisation; potentially inappropriate application of simple imputation.
Unclear: Insufficient information to permit judgement
Selective reporting
Reporting bias due to selective outcome reporting
Low risk of bias: The study protocol is available and all of the study’s pre‐specified (primary and secondary) outcomes that are of interest in the review have been reported in the pre‐specified way; the study protocol is not available but it is clear that the published reports include all expected outcomes, including those that were pre‐specified (convincing text of this nature may be uncommon).
High risk of bias: Not all of the study’s pre‐specified primary outcomes have been reported; one or more primary outcomes is reported using measurements, analysis methods or subsets of the data (e.g. sub‐scales) that were not pre‐specified; one or more reported primary outcomes were not pre‐specified (unless clear justification for their reporting is provided, such as an unexpected adverse effect); one or more outcomes of interest in the review are reported incompletely so that they cannot be entered in a meta‐analysis; the study report fails to include results for a key outcome that would be expected to have been reported for such a study.
Unclear: Insufficient information to permit judgement
Other bias
Bias due to problems not covered elsewhere in the table
Low risk of bias: The study appears to be free of other sources of bias.
High risk of bias: Had a potential source of bias related to the specific study design used; stopped early due to some data‐dependent process (including a formal‐stopping rule); had extreme baseline imbalance; has been claimed to have been fraudulent; had some other problem.
Unclear: Insufficient information to assess whether an important risk of bias exists; insufficient rationale or evidence that an identified problem will introduce bias.

Appendix 3. Outcome definitions

Outcome Definition
ADL: Activities of Daily Living Eight questions: they range from 0, meaning they have no difficulty, to 2, which means they can not do it even with help
Asthenia Scored as slight if fatigue appeared at less than 60 sec of exercise A and at less than 30 ascents and descents during exercise B, intense at less than 15 sec of exercise A and at less than 10 ascents and descents of exercise B. Moderate degree of asthenia was between the two extremes
BAI: Beck Anxiety Inventory 21 questions about how the subject has been feeling in the last week expressed as common symptoms of anxiety. Each question has the same set of four possible answer choices (0 (never) and 3 (critically)). The total score ranges from 0 to 63 points, with higher scores meaning more anxiety
BDI: Beck Depression Inventory 21‐question multiple‐choice self‐report inventory for measuring the severity of depression. The total score ranges from 0 to 63 points, with higher total scores indicating more severe depressive symptoms
BFI: Brief Fatigue Inventory Checklist with 10 questions so that the first question asks if the respondents had felt fatigue over the last week. Other questions ask about level of fatigue felt by the respondent at the time, normal and highest level of fatigue over the past 24 h, and the effects of fatigue on their general activity, mood, ability to walk, communicate with others, and enjoying life. The questions are designed based on an 11‐point scale (0‐10) so that 'zero' is the best possible condition and 10 is the worst. Eventually, total fatigue level of the patient is calculated as the total score of the questions 2‐10 (9 questions) divided by nine
Bouchard's PAL Activities are categorized into 9 levels, with 1 as the least intense (0.26 kcal/kg/15 min) and 9 as the highest intensity (1.96 kcal/kg/15 min
CES‐D: Center for Epidemiologic Studies Depression Scale Scores ≥ 16 indicate clinically meaningful symptoms
COPM: Canadian Occupational Performance Measure Individuals asked to rate, on a 10‐point Likert scale, his/her performance in each of three self‐selected priority activities of everyday living. Higher scores out of 10 indicate better performance/satisfaction with performance
Cramps Frequency, severity, site, and duration of the cramps were recorded and scored as slight when they lasted less than 5 mm; moderate 5 to 10 mm; intense more than 10 mm
ENRICH questionnaire One of these 10 items assessed sexual satisfaction. The total score was the sum of positive and negative items and ranged from 10 to 50
EQ‐5D: EuroQol‐5 dimension health questionnaire Number 1 indicates the best state of health (perfect health) and 0 the worst state of health (death)
Fatigue Management Questionnaire Individuals asked to rate various aspects of their fatigue management (e.g. overall impact on life participation; satisfaction; self‐efficacy), out of 10, on 5‐point Likert‐scale questions. Scores are then summed and averaged for each of two subscales (Performance Subscale and Satisfaction Subscale), with higher scores out of 10 indicating better fatigue management)
Fatigue score HD patients fatigue scale developed by Chung and Kao: fatigue was measured on a five‐point rating scale inquiring about 25 essential symptoms of fatigue, with 5 indicating the most fatigue and 1 the least
FI: Fatigue Index questionnaire Each domain rated from 1 to 5, recorded hourly during the entire study period on a fatigue intensity form as follows: 0, none; 1, mild (noticeable but without effect); 2, moderate (felt sluggish); 3, severe (required rest); or 4, overwhelming (slept). The maximal fatigue score recorded within 6 hours after dialysis or at similar time periods on non‐dialysis days (baseline) was used to rate the level of fatigue for the period in question
FSS: Fatigue Severity Score Nine questions, which questions 1–4 and 6 focus on the quality of fatigue, questions 5–7 and 9 are about physical and mental fatigue and their effects on the social life of individuals, and question 8 measures the severity of fatigue. The score range for each question is between 1 and 7, with a score of 1 for absolute disagreement and a score of 7 for absolute agreement. The total score range of the questionnaire is between 7 and 63, so a score of 36 or higher is an indication of fatigue. Hence, higher scores are indicative of higher fatigue
GAD: Generalized Anxiety Disorder Brief 7‐item self‐report scale on the basis of Diagnostic and Statistical Manual of Mental Disorders‐IV criteria for generalized anxiety disorder, with items scored from 0 (not at all) to 3 (nearly every day)
HADS: Hospital Anxiety and Depression Scale 14‐item self‐report screening scale that comprises 7 items for each of the Anxiety and Depression subscales.

IFS: Iowa Fatigue Scale Eleven questions determined the level of fatigue (four questions were in cognitive aspects, a pair of questions were about physical fatigue, three questions were about energy rate and pair of questions were about work output). Fatigue score range was from 11 to 55. Score indicated the minimum fatigue rate, and 55 was maximum rate
IPOS‐Renal: Integrated Palliative Outcome Scale‐Renal All symptoms cores are reported on a 0 to 4 scale (0=not at all, 1=slightly, 2=moderately, 3=severely, 4=overwhelmingly bothered) and indicate the effect of the symptom on the respondent over the past week
ItchyQoL: QoL questionnaire fo patients with pruritus Consists of 27 questions. The answers to each question consist of five levels: never, rarely, sometimes, often, and always, which are scored from 1 to 5, respectively
KDQ: Kidney Disease Questionnaire Follows a 7‐point Likert‐type scale (7 = no problem, 1 = a severe problem) with higher scores indicating better health‐related quality of life. A clinically meaningful difference in KDQ score was a 0.5 point change, and a mean change of 1.0 represented a large clinical change
KDQOL‐SF: Kidney Disease Quality of Life‐Short Form 43 items related to the quality of life in relation to kidney patients, with 36 items related to general health.

LEVIL: London Evaluation of Illness Subject responses were rated from 0 (worst symptoms) to 100 (no symptoms
MFI‐20: Multidimensional Fatigue Inventory Each dimension includes four items, and responses are score based on a 5‐point Likert scale from strongly agree to strongly disagree. Higher scores indicate greater fatigue. Total score of each dimension ranges between 4 and 20, and the total fatigue score ranges between 20 and 100. Scores of 20‐41 indicate mild fatigue, scores of 48‐74 indicate moderate fatigue, and scores of 75‐100 indicate severe fatigue

PFS: Piper Fatigue Scale Includes a total of 27 items and evaluates subjective perception of the patients on fatigue under four subscales. Responses for each item were scored between 0‐10 points. The total fatigue score was obtained by summing the points of 22 items, then dividing the sum into the number of items. High scores signify a high level of perceived fatigue
PROMIS‐Fatique Short Form Seven items about energy or exhaustion
PSQI: Pittsburgh Sleep Quality Index Scale comprised 18 items and 7 component scores. Every component was evaluated from 0 to 3. The total of these component points yielded the total score of the scale, which ranged from 0 to 21. A high score (5 or above) indicated poor sleep quality. Sleep quality classified as good (0–4) and poor (5–21)
RNLI: Reintegration to Normal Living Index Assesses the degree to which individuals who have experienced traumatic or incapacitating illness achieve reintegration into normal activities, using 11 declarative statements each accompanied by a 10‐point visual analogue scale. Scores are then added to produce an overall score out of 110, with higher scores indicating better reintegration to normal living
SF‐12: 12‐item Short Form Health Survey Higher Mental Component Scores and Physical Component scores indicate better HRQoL
SF‐36: 36‐item Short Form Health Survey Eight subscales include physical function, role limitation due to physical problems, social function, role limitation due to emotional problems, mental health, fitness/fatigue, pain, and understanding of general health. By calculating the scores obtained from the subscales, 2 main scale scores are obtained; physical and mental scales. Each subscale score ranges from 0 to 100. The physical and mental scale scores are also between 0 and 100. Zero indicates the worst and 100 indicates the best health condition
SMMT: Standardized Mini Mental Test Covers five main areas and consists of 11 items, takes approximately 10 min to complete. The highest score obtainable from the SMMT is 30. In the SMMT, a score of 24–30 points is considered normal, 20–23 is considered to indicate light/mild dementia, 10–19 to indicate intermediate/mid‐stage dementia, and 0–9 to indicate advanced dementia

SONG‐HDF: Standardised Outcomes in Nephrology‐Haemodialysis Fatigue Assesses the severity of fatigue, and its impact on daily living, in people on maintenance haemodialysis using 3 Likert‐style questions. Scores are summed to produce a total score out of 9, with higher scores indicating worse fatigue
STAI / STAI‐Y1: State‐Trait Anxiety Inventory Composed of 20 items concerning state anxiety. 4‐point Likert scale: 1 = “not at all”; 2 = “a little”; 3 = “enough”; and 4 = “very much.” The final score is obtained by sum of the responses to the individual items and can vary from a minimum of 20 to a maximum of 80. A higher score indicates a greater level of anxiety in the subject) with scores ≥ 40 indicating elevated anxiety
Symptoms related to orthostatic hypotension questionnaire Assessed using a 4‐point rating scale; severe (daily activities were greatly disturbed by the symptom), moderate (daily activities were disturbed by symptoms), mild (patients were aware of the symptoms, but daily activities were not disturbed), and asymptomatic (there was no symptom at all and patients were not bothered by any symptoms). The improvement for each symptom or the global improvement rating was assessed using a 6‐point rating scale (marked improvement (4 or higher), moderate improvement (3 or 2 and if patients have no new symptoms), slight improvement (2 or 1 and if patients have no new symptoms), no changes (±1, 0), aggravation (‐2 or less, or if patients develop new symptoms), asymptomatic (if patients have no new symptoms)
VAS: Visual Analogue Scale Numbers were placed at equal intervals on a horizontal line. The presence of the worst value was rated the highest point (e.g. 10 on a 10‐point scale)
Example: 1‐3 mild; 4‐6 moderate; 7‐10 severe

Nonserious adverse events were more frequent in the sertraline (56 events in 25 patients) than the CBT (17 events in 12 patients) group."
ASSertID 2015 Sertraline Placebo Adverse events and/or serious adverse events (9/15); cardiovascular death (1/15) Adverse events and/or serious adverse events (9/15); cardiovascular death (0/15) Quote: "Eighteen patients experienced adverse events (24) and/ or SAEs (13), nine in each randomized group. Infections (8) and nausea (4) were the most commonly reported adverse events. With regard to the SAEs, there was one death that was possibly related to the study medication as mentioned above, six SAEs that were unlikely to be related, and six SAEs that were not related to the study medication." "In the sertraline group, there were six dropouts within the first 2 months. One patient died of cardiac arrest having taken one tablet. Three patients withdrew because of adverse events (one after 3 days with nausea, another after 12 days with headaches and dizziness, and the third due to insomnia after 23 days). The fifth patient withdrew because of concern about side effects, having taken no study medication. The sixth patient was admitted for a prolonged hospital stay with leg ulcers shortly after randomisation and subsequently withdrawn without having taken any study medication. At 3 months, a seventh patient withdrew because of sweating and palpitations. In the placebo group, one patient withdrew after the baseline interview because of concern about taking additional medication, and a second decided against continuing after 3 months."

All cases of anaemia were considered to be related to study medication, whereas the kidney transplant was not. There were 5 withdrawals because of AEs in the extension period (pruritus, chest pain, rectal cancer, accelerated hypertension, and cerebrovascular accident [1 patient each]). In addition, dialysis was discontinued in 1 patient (at the request of her
family), who was subsequently withdrawn from the study. The investigator classified this as an AE of chronic renal failure. All AEs leading to withdrawal in the extension period were considered to be unrelated to the study medication with the exception of accelerated
hypertension (1 patient), which was classified as an SAE. Nineteen patients experienced an SAE during the core period, and 22, during the extension period. Two patients died during the extension period of the
study (acute myocardial infarction and multiple organ failure); these deaths were deemed as SAEs. Neither death was considered related to treatment."

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "Random block of numbers. Block randomisation was conducted as follows: the group of aromatherapy with lavender essential oil was given the code “A,” the group of aromatherapy with orange essential oil was given the code “B,” and the group of distilled water was given the code “C.” Then, six blocks of three were formed: ABC, ACB, BAC, BCA, CAB, and CBA. In order to select the groups, block BAC was randomly selected. Thus, on the first day (which was Saturday), 30 subjects were assigned to the group of aromatherapy with orange essential oil. On Sunday, 30 subjects were assigned to lavender essential oil group and finally on Monday, another 30 subjects were assigned to the control group."
Comment: random numbers are considered at low risk of bias
Allocation concealment (selection bias) Low risk Quote: "The names of subjects in each group were registered in the coming days. The statistical adviser of the study (second author) was responsible for determining the blocks, and the subjects were allocated into the study groups by the first author."
Blinding of participants and personnel (performance bias)
All outcomes High risk Quote: "There was no possibility of blinding subjects for the type of the assigned group."
Blinding of outcome assessment (detection bias)
All outcomes High risk Fatigue was assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. No other outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes Low risk All participants completed the study. No lost to follow‐up were reported
Selective reporting (reporting bias) High risk Protocol was published. It was reported if multiple eligible outcome measurements (scales and time points) were pre‐specified. It was unclear if the reported approach to analysing this outcome was pre‐specified or influenced by the results. Fatigue data were cumulated for 2 RCTs, all time points were not reported. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Low risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding did not influence the data analysis and conflicts of interest were not reported. No other source of bias were apparent

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Unclear risk Sequence generation methods were not reported in sufficient detail to permit judgement
Allocation concealment (selection bias) Unclear risk Method of allocation concealment was not reported in sufficient detail to permit judgement
Blinding of participants and personnel (performance bias)
All outcomes Unclear risk Quote: "Double‐blind design."
Comment: Although the author reported that the study used a double‐blind design, information about blinding of participants and investigators was not clearly stated
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "Eight subjective symptoms related to orthostatic hypotension (fatigability, malaise/weakness, physical disturbing on standing up, dizziness on standing up, bad feeling, sleep disorder) were monitored through doctor's questions, based on notebooks kept by the patients. The severity of each symptom was separately assessed using a 4‐point rating scale, i.e. severe (daily activities were greatly disturbed by the symptom), moderate (daily activities were disturbed by symptoms), mild (patients were aware of the symptoms, but daily activities were not disturbed), and asymptomatic (there was no symptom at all and patients were not bothered by any symptoms)."
Comment: Fatigue was assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk Quote: "Of the 149 patients, 5 were excluded from efficacy assessment due to missing blood pressure data, and 3 were also excluded because L‐DOPS therapy was discontinued within 2 weeks of the trial. A total of 141 patients (400 mg group 48 patients, 200 mg group 46 patients, and placebo group 47 patients) were thus subjected to efficacy assessment."
Comment: 48/51 participants in intervention group 1 (400 mg L‐DOPS), 46/49 participants in intervention group 2 (200 mg L‐DOPS) and 47/49 participants in the control group (placebo) completed the study (> 5% lost to follow‐up, whit differences between groups). In addition, some analyses were reported on a lower number of participants
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan was not reported. It was not reported if multiple eligible outcome measurements (scales and time points) were pre‐specified. It was unclear if the reported approach to analysing this outcome was pre‐specified or influenced by the results. Fatigue at the end of treatment was reported in a format that was not extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias High risk There was no evidence of different baseline characteristics or different non‐randomised co‐interventions between groups. Funding (pharmaceutical company) could influence the data analysis, and conflicts of interest were not reported.

Comment: Computer‐generated is considered as low risk of bias
Allocation concealment (selection bias) Low risk Quote: "Randomizations were performed through a Web portal by using computer‐generated permuted blocks of various sizes."
Comment: Web portal is considered as low risk of bias
Blinding of participants and personnel (performance bias)
All outcomes High risk Quote: "Open‐label."
Comment: An open‐label study is considered at high risk of bias
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "An independent group charged with monitoring the safety of patients in the ASCEND trial, and the scientific integrity of the trial (unblinded)."
Quote: "Randomized participants undergo blinded serial assessment of depressive symptoms every 6 weeks using the clinician‐rated 16‐item Quick Inventory of
Depression Symptomatology (QIDS‐C16) administered by research personnel blinded to intervention arm, via a Computer Assisted Telephone Interview (CATI)."
Comment: Fatigue was assessed with an appropriate measure, without differences between groups. However, subjective measures were used. It was not stated whether outcomes were assessed without knowledge of treatment allocation (it was stated that a blinded interviewer assessed the QIDS‐C16, but no information was reported for the assessment of the fatigue questionnaire), and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. Other subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes Unclear risk Quote from Merhotra 2019: "Of the 636 patients with a BDI‐II score of 15 or above, 310 (49%) consented to screening and 184 were randomly assigned to the engagement (n = 92) or control (n = 92) group. Of these participants, 120 were randomly assigned to the CBT (n = 60) or sertraline (n = 60) group, 20 who declined treatment within or outside the study enrolled in the observation group, and 44 withdrew from the study."
Comment: Although some participants withdrew, all were included in the analysis
Selective reporting (reporting bias) Low risk Information about the protocol and the statistical analysis plan was reported. Multiple eligible outcome measurements (scales and time points) were assessed as pre‐specified in the study protocol. Fatigue at the end of treatment was reported in a format that was not extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were reported
Other bias High risk Quote: "The funding organizations had no input in the analysis or interpretation of the data, the drafting of the manuscript, or the decision to submit the manuscript for publication."
Comment: Similar baseline characteristics between groups were reported. Funding was unlikely to influence the data analysis and reporting. However, conflicts of interest were reported

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote from Friedli 2015 (protocol): "Randomisation will take place in blocks using pre‐prepared codes for each centre. These will be incorporated into a protected web based randomisation programme prepared by Norwich CTU."
Comment: Sequence generation methods seemed to use a computer. No data were available to assess the possible imbalance between groups
Allocation concealment (selection bias) Low risk Quote from Friedli 2015 (protocol): "Randomisation will take place in blocks using pre‐prepared codes for each centre. These will be incorporated into a protected web based randomisation programme prepared by Norwich CTU. Only the research psychiatrist will have authorised access to the online randomisation programme. Following randomisation the relevant pharmacy will be informed of the allocation (treatment A or B) by automatically generated email. The pharmacist will be blind to the allocation. The CTU will hold the patient‐specific allocation data on a secure server. The CI and PI at each centre will have access to this data file only via a special log‐in should the need arise to un‐blind. No user identifiable data will stored in the randomisation database. Web traffic will be encrypted using standard secure sockets layer technology."
Comment: A web‐based system is considered as low risk of bias. No data were available to assess the possible imbalance between groups
Blinding of participants and personnel (performance bias)
All outcomes Low risk Quote from Friedli 2017: "The patients, dispensing pharmacies, study psychiatrist, research nurses, all clinicians, trial manager, and study statistician were blind to the allocation of the study medication."
Comment: A double‐blind study is considered as low risk of bias
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote from Chilcot 2017: "Fatigue was assessed using the MFI‐20."
Comment: fatigue was assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk Quote: "Twenty‐one (70%) patients completed the trial: eight (53%) in the sertraline group and 13 (87%) in the placebo group (P=0.05). In the sertraline group, there were six dropouts within the first 2 months. One patient died of cardiac arrest having taken one tablet. Three patients withdrew because of adverse events (one after 3 days with nausea, another after 12 days with headaches and dizziness, and the third due to insomnia after 23 days). The fifth patient withdrew because of concern about side effects, having taken no study medication. The sixth patient was admitted for a prolonged hospital stay with leg ulcers shortly after randomisation and subsequently withdrawn without having taken any study medication. At 3 months, a seventh patient withdrew because of sweating and palpitations. In the placebo group, one patient withdrew after the baseline interview because of concern about taking additional medication, and a second decided against continuing after 3 months. The number of dropouts due to adverse or severe adverse events was greater in the sertraline group."
Comment: overall, 21/30 participants completed the study (>5% lost to follow‐up, differences between groups). Some reasons for discontinuations could be related to the treatment assigned
Selective reporting (reporting bias) High risk Protocol was published. Trial registration number reported that fatigue should be assessed using MFI‐20 and SF‐36 energy/fatigue sub scale, but data were reported only using MFI‐20. It was unclear if the reported approach to analysing this outcome was pre‐specified or influenced by the results. Fatigue at the end of treatment was reported in a format that was not extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Low risk Similar baseline characteristics between groups were reported. Funding was unlikely to influence the data analysis and reporting and authors had no conflicts of interest

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Unclear risk Sequence generation methods were not reported in sufficient detail to permit judgement
Allocation concealment (selection bias) Unclear risk Method of allocation concealment was not reported in sufficient detail to permit judgement
Blinding of participants and personnel (performance bias)
All outcomes High risk Not reported. However, interventions were different and participants and/or investigators could be aware of the treatment assigned
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "Data were collected using a demographic questionnaire and the Multi‐dimensional Fatigue Inventory (MFI‐20)."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely
Incomplete outcome data (attrition bias)
All outcomes High risk The number of patients who completed the study was not clearly stated for the first phase. It was unclear if there was evidence that the results were not biased by missing outcome data
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan were not reported. It was not reported if multiple eligible outcome measurements (scales and time points) were pre‐specified. It was unclear if the reported approach to analysing this outcome was pre‐specified or influenced by the results. Fatigue at the end of treatment was not reported in a format that was extractable for meta‐analysis (cross‐over study: data related to the first period were not reported). All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Unclear risk No data were available to assess the possible imbalance between groups. Funding was unlikely to influence the data analysis and conflicts of interest were not reported

Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Unclear risk Quote: "Dialysis was performed in random sequence with dialysate sodium of 145, 150, or 155 mEq/L for 2 months at a time."
Comment: Sequence generation methods were not reported in sufficient detail to permit judgement

Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "Objective examination of asthenia consisted in making the patient flex the knees with the trunk in upright position for different intervals (exercise A) and walk repeatedly up band down three steps (exercise B). Asthenia was scored as slight if fatigue appeared at less than 60 sec of exercise A and at less than 30 ascents and descents during exercise B, intense at less than 15 sec of exercise A and at less than 10 ascents and descents of exercise B. Moderate degree of asthenia was between the two extremes. The exercises were performed immediately after and between haemodialysis. In the latter case the patients did the exercises at home and recorded the results."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting.

All outcomes High risk Quote: "The patient data relating to the questionnaire, VAS pain (measurement of pain level), VAS fatigue, and Piper fatigue scale at the first follow‐up (the first interview before acupressure) were collected by the researcher."
Comment: Fatigue was assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely.

Incomplete outcome data (attrition bias)
All outcomes High risk Quote: "A total of 150 patients, meeting the inclusion criteria, were reached during the study. Five patients in the intervention group did not agree to participate in the study. Two of these patients experienced local pruritus in the area the device was applied, one patient developed a fistula problem, and two patients left the city during the follow‐up. Additionally, three patients in the placebo group did not want to continue the study since two of these patients were receiving treatment in a hospital out of the city due to coronary angiography. Therefore, the study was completed with 135 patients."
Comment: 135/150 participants completed the study (> 5% loss to follow‐up. Some reasons for discontinuation were provided, and some were related to the intervention

Blinding of participants and personnel (performance bias)
All outcomes Unclear risk Quote: "Two placebo‐controlled, double‐blinded, randomised studies of carnitine supplementation were performed."
Comment: Although author reported that the study used a double‐blind design, information about blinding of participants and investigators were not clearly stated
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "The Kidney Disease Questionnaire (KDQ) is a validated questionnaire for measuring quality of life in patients with ESRD. It was administered in English or Spanish by trained interviewers on non dialysis days. [...] A standardized chemistry panel was assessed during screening, at baseline, and after 12 and 24 weeks of treatment."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk Quote: "Study A randomised 60 patients, 30 patients on each study arm. Four patients (2 patients from each group) were excluded from the intention‐to‐treat population because they withdrew before and post baseline exercise tests (2 patients received renal transplants, 1 patient relocated, and 1 patient withdrew after developing elevated serum transaminase levels). Within the intention‐to‐treat population (n = 56), 7 patients (1 patient, placebo; 6 patients, L‐carnitine) withdrew before completing the 24‐week protocol. Three patients received renal transplants, 1 patient withdrew consent, 1 patient became pregnant, 1 patient was unable to perform the exercise test, and 1 patient withdrew from the study after a serious adverse event unrelated to study drug. Study B randomised 133 patients. Six patients (all administered carnitine) did not have post baseline exercise assessments and were thus excluded from the intention‐to‐treat population (2 patients received renal transplants, 1 patient withdrew from the study, 1 patient experienced worsening of arthralgia, 1 patient died, and 1 patient withdrew because of ECG changes). Within the intention‐to‐treat population (n = 127), 9 patients (2 patients, placebo; 3 patients, 10 mg/kg of L‐carnitine; 2 patients, 20 mg/kg of L‐carnitine; 2 patients, 40 mg/kg of L‐carnitine) failed to complete the full 24‐week study. One patient had exercise‐related problems, 1 patient was unable to exercise because of carpal tunnel syndrome, 4 patients received renal transplants, 1 patient withdrew because of back spasms, I patient refused the study drug because of abdominal pain, and 1 patient withdrew because of ECG changes."
Comment: 11/60 in the study A did not complete the study (> 5% lost to follow‐up, with differences between groups). Reasons for discontinuations seemed to be not related to the treatment allocation. 15/133 in the study B did not complete the study (>5% lost to follow‐up, with differences between groups). Reasons for discontinuations seemed to be not related to the treatment allocation
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan were not reported. It was not reported if multiple eligible outcome measurements (scales and time points) were pre‐specified. It was unclear if the reported approach to analysing this outcome was pre‐specified or influenced by the results. Fatigue data were cumulated for 2 RCTs, all time points were not reported. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias High risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding (pharmaceutical company) could influenced the data analysis and conflicts of interest were not reported

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote from Canadian EPO 1990: "Patients were stratified by hospital and randomised in blocks to receive placebo; erythropoietin at a dose adjusted to maintain the haemoglobin concentration at 95‐110 g/l (low erythropoietin group); or erythropoietin at a dose adjusted to maintain the haemoglobin concentration at 115‐130 g/l (high erythropoietin group)."
Comment: sequence generation methods were not reported in sufficient detail to permit judgement
Allocation concealment (selection bias) Unclear risk Quote from Canadian EPO 1990: "Patients were stratified by hospital."
Comment: method of allocation concealment was not reported in sufficient detail to permit judgement
Blinding of participants and personnel (performance bias)
All outcomes Low risk Quote from Canadian EPO 1990: "To ensure that the study was double blind we established two teams of staff at each study centre. The unblinded team consisted of a doctor, a pharmacist, and a data clerk and was responsible for adjusting the dose of erythropoietin, prescribing iron supplements or transfusions, and sending haematological data to the coordinating centre. The blinded team consisted of nurses in the dialysis unit and our study group and all doctors in the dialysis unit other than those in the unblinded team; this team carried out routine clinical care and recorded adverse reactions and other clinical events but did not have access to the results of haematological tests or know the dose of erythropoietin or placebo that each patient was receiving."
Comment: a clear explanation of the double‐blind study was provided
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote from Canadian EPO 1990: "The nurses in the study group administered tests to assess quality of life and exercise capacity."
Quote from Keown 2010: "Health‐related quality of life was measured by the Kidney Disease Questionnaire (KDQ) and Sickness Impact Profile (SIP) between the placebo group and the combined Epoetin alfa‐treated group."
Comment: the outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used (although nurses were part of the blinded team) it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes Unclear risk Quote from Canadian EPO 1990: "Nineteen patients were withdrawn during the study: eight in the placebo group (because of transplantation (five), non‐compliance (one), reaction to transfusion (one), seizure and death (one)); six in the low erythropoietin group (transplantation (two), hypertension (one), hypertension and seizure (one), subarachnoid haemorrhage and seizure (one), pregnancy (one)); and five in the high erythropoietin group (transplantation (three), hypertension (two)). Six patients were withdrawn before the follow‐up at two months, and the 13 others were withdrawn before the follow‐up at four months. The patient who became pregnant continued to receive erythropoietin but had a spontaneous miscarriage at 11‐ 1 2 weeks' gestation."
Quote from Muirhead 2008: "Analysis was conducted using ITT."
Comment: 11/78 in the two intervention groups and 8/40 in the placebo group did not completed the study. However, ITT analyses was performed
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan were not reported. Fatigue was reported using multiple eligible outcome measurements (scales, time points). Fatigue was reported in a format that was extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias High risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding (pharmaceutical company) could influenced the data analysis and authors had conflicts of interest

Incomplete outcome data (attrition bias)
All outcomes Low risk Quote: "The patients involved in the preliminary application were included in the number of samples and new patients who met the criteria in each group of 28 patients were included in the groups by computerized randomisation and a total of 84 patients was reached. Since one patient from the hand massage group left the dialysis canter temporarily after the fifth massage session, and one patient from the foot massage group died after being taken to the intensive care prior to the fourth session, one patient from each group was excluded from the research. As a result, a total of 82 patients, including 27 patients in each of the hand massage and foot massage groups, and 28 patients in the control group, formed the sample of the research."
Comment: 54/56 participants in the intervention groups and 28/28 in the control group completed the study (< 5% loss to follow‐up). Differences between subgroups were reported. Reasons for discontinuation were reported
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan was not reported.

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) High risk Quote: "This was a quasi‐experimental clinical trial in a medical centre with two haemodialyses units managed by the same medical and nursing team. The patients were assigned randomly to either unit. The experimental group was recruited from one unit and the control group from another, and participants were pair‐matched based on age and gender."
Comment: Since the study was a quasi‐experimental trial, no random element was used in generating the allocation sequence or the sequence was predictable
Allocation concealment (selection bias) High risk Method of allocation concealment was not reported in sufficient detail to permit judgement. However, since the study was a quasi‐experimental trial, there was a reason to suspect that the enrolling investigator or the participant had knowledge of the forthcoming allocation.

Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "Subjects were interviewed by a research assistant to fill‐out the fatigue scale and Bouchard’s PAL on enrolment, during the fourth week and the eighth week of their haemodialysis visits. The research nurse is not a staff working in these haemodialysis units. She collected data independently and did not participate in patient care."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant/investigators beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely.

Incomplete outcome data (attrition bias)
All outcomes High risk Quote: "From August to November 2008, there were 44 and 46 subjects in each unit who met the criteria and were invited to participate. Fourteen refused in the beginning as they were unwilling to participate. Five subjects dropped‐out in later stages for various reasons (Figure 1). Thirty‐six subjects (80%) in the experimental group and 35 patients (76%) in the control group completed the study."

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "We randomly assigned participants by using computer generated randomised numbers with an allocation ratio of 1:1; to either the CBT group (13) or the control group (13). No stratification or blocking factors were used."
Comment: Computer generated randomised numbers is considered as low risk of bias. No imbalance between intervention groups was apparent
Allocation concealment (selection bias) Unclear risk Quote: "The sequence was concealed until the interventions were assigned. [...] The generation of allocation sequence and assignment of participants was performed by the project director."
Comment: It was not stated if the enrolling investigator (project director) had knowledge of the forthcoming allocation. No imbalance between intervention groups was apparent
Blinding of participants and personnel (performance bias)
All outcomes High risk Quote: "This pilot study did not use a double‐blind design, and participants were informed of their allocation sequence by telephone."
Comment: An open‐label study is considered as high risk of bias. Interventions were different and participants and/or investigators were aware of the treatment assigned
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "Fatigue was assessed using a questionnaire. The 2 measurements were completed before and after the 4‐week trial by all participants in both groups."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes Unclear risk Quote:"Two participants in the control group withdrew after randomisation for personal considerations (1 person lived too far from the hospital, and the other needed to work in the night‐time during the trial."
Comment: Although 2/13 participants withdrawal from the control group, Figure 1 and Table 4 showed that all patients were included in the analysis
Selective reporting (reporting bias) High risk Protocol was provided. Fatigue was reported using multiple eligible outcome measurements (scales, time points). Fatigue was reported in a format that was extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "We randomised participants by computer‐generated random numbers with an allocation ratio of 1:1; that is, either to the CBT group or to the control group."
Comment: Computer‐generated randomised numbers is considered as low risk of bias. No imbalance between intervention groups was apparent
Allocation concealment (selection bias) Unclear risk Quote: "The generation of allocation sequence and assignment of participants was performed by the project director."
Comment: It was not stated if the enrolling investigator (project director) had knowledge of the forthcoming allocation. No imbalance between intervention groups was apparent
Blinding of participants and personnel (performance bias)
All outcomes High risk Quote: "This study was an open‐labelled design. Participants were informed of their allocation sequence by the nursing staff, and the sequence was concealed until the interventions were assigned."
Comment: An open‐blinded study is considered as high risk of bias
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "Fatigue was assessed using a questionnaire. The four measurements were completed before and after the 6‐week trial by all of the participants in both groups."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk Quote: "After randomisation, three participants in the CBT group and five participants in the control group refused to participate and withdrew their informed consent because of personal considerations. Therefore, a total of 72 subjects (37 in the CBT group and 35 in the control group) participated."
Comment: 37/40 participants in the intervention group and 35/40 participants in the control group completed the study (> 5% lost to follow‐up, with differences between groups). Reasons for discontinuations seemed to be not related to the treatment allocation
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan were not reported. Fatigue was reported using multiple eligible outcome measurements (scales, time points). Fatigue was reported in a format that was extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Low risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding was unlikely to influence the data analysis and authors had no conflicts of interest. The study seemed to be free from other source of bias

Comment: Fatigue was assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk 8/15 participants in the intervention group and 14/15 participants in the control group completed the study (> 5% lost to follow‐up). There were differences between treatment groups. Reasons for discontinuation were provided
Selective reporting (reporting bias) High risk Protocol was published. Fatigue was reported in accordance with a pre‐specified analysis plan, using multiple eligible outcome measurements (scales, time points). Fatigue was reported in a format that was not extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Low risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding was unlikely to influence the data analysis and authors had no conflicts of interest. No other source of bias were apparent

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Unclear risk Sequence generation methods were not reported in sufficient detail to permit judgement
Allocation concealment (selection bias) Unclear risk Method of allocation concealment was not reported in sufficient detail to permit judgement
Blinding of participants and personnel (performance bias)
All outcomes Unclear risk Quote: "Twelve haemodialysis patients received either L‐carnitine (20 mg/kg‐1 IV) or placebo in a double‐blind, placebo‐controlled, counterbalanced, and cross‐over design for 8 weeks."
Comment: Although the author reported that the study used a double‐blind design, information about blinding of participants and investigators were not clearly stated
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "In their second visit, subjects returned their diet recall forms and underwent a progressive diagnostic test to exhaustion (GXT) on a stationary cycle ergometer to evaluate their peak oxygen consumption (VO2 peak) while blood was collected before and immediately after testing."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk Attrition was not reported in sufficient detail to permit judgment in the first phase of the study
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan was not reported. It was not reported if multiple eligible outcome measurements (scales and time points) were pre‐specified. It was unclear if the reported approach to analysing this outcome was pre‐specified or influenced by the results.

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote from Suri 2007: "Eligible subjects are then randomly assigned 1:1 to the frequent haemodialysis intervention or control arms, by a central, web‐based program. Randomization is stratified by clinical centre and diabetic status, using permuted blocks."
Comment: A web‐based program is considered as low risk of bias. No imbalance between intervention groups was apparent
Allocation concealment (selection bias) Unclear risk Quote from FHN Trial Group 2010: "Randomization was stratified according to clinical centre and diabetes status, with the use of randomly permuted blocks. Although treatment assignments could not be concealed, between group comparisons of the outcomes were concealed from the investigators throughout the course of the trial."
Blinding of participants and personnel (performance bias)
All outcomes High risk Quote from Kuella 2013: "Unblinded intervention."
Comment: An open‐label study is considered as high risk of bias. Possible deviations from the intended intervention that arose from the trial context were not reported
Blinding of outcome assessment (detection bias)
All outcomes Low risk Quote from Suri 2013: "A vascular access outcomes committee blinded to group allocation reviewed all access events to determine whether the event met the definition of repair or loss. [...] An independent outcomes committee blinded to group allocation reviewed these forms, discharge summaries, and supplementary chart information to determine whether each death or hospitalisation was access related or non–access related."
Quote from Suri 2014: "Patients also completed several questionnaires that were centrally administered by telephone before randomisation and 4 (F4) and 12 months (F12) after randomisation."
Quote from Ornt 2013: "An independent data and Safety Monitoring Board reviewed safety data and interim results."
Comment: An independent Data Safety Monitoring Board assessed the outcomes.The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was stated that outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may not have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely
Incomplete outcome data (attrition bias)
All outcomes High risk Overall, attrition seemed to be > 5% of loss to follow‐up with some difference between groups. Attrition was not reported in sufficient detail to permit judgment in the first phase of the study. Tamura 2010 reported that 239 participants were randomised but there were no data on the missing participants

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Unclear risk Sequence generation methods were not reported in sufficient detail to permit judgement.
Allocation concealment (selection bias) Low risk Quote: "Randomisation was performed using individual allocation codes placed within opaque, sealed envelopes by a person having no contact with the participants."
Blinding of participants and personnel (performance bias)
All outcomes High risk Not reported. However, interventions were different and participants and/or investigators could be aware of the treatment assigned.
Blinding of outcome assessment (detection bias)
All outcomes High risk Fatigue was assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant/investigators beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. It was not stated if the monitoring group was blinded to the treatment assigned. However, objective and subjective outcomes were assessed.
Incomplete outcome data (attrition bias)
All outcomes Unclear risk Quote: "Intention‐to‐treat."
Comment: 10/11 participants in the intervention group 1 (IMT), 10/13 participants in the intervention group 2 (at), and 11/13 participants in the intervention group3 3 (combination) completed the study. However ITT was performed.
Selective reporting (reporting bias) Low risk Information about the protocol and the statistical analysis plan were reported. Fatigue was reported using multiple eligible outcome measurements (scales, time points). Fatigue was reported in a format that was not extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were reported, but fatigue was not extractable.
Other bias Low risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding was unlikely to influence the data analysis and authors had conflicts of interests. No other source of bias were apparent.

Blinding of participants and personnel (performance bias)
All outcomes High risk Quote from Foley 2000: "This was a 48‐week, open‐label, randomised, controlled trial."
Comment: An open‐label study was considered as high risk of bias
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "A study monitoring group (R.N.F., P.S.P., and J.M.) at the coordinating centre in St. John’s met weekly to review each patient’s haemoglobin level, epoetin dose, iron saturation, and blood pressure level."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting (bot sure if the committee assessed also fatigue). Participant/investigators beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. It was not stated if the monitoring group was blinded to the treatment assigned. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk Quote: "Follow‐up studies were unavailable in 12 patients, 5 in the low target and 7 in the high target group. The reasons included transplantation (3), death (3), withdrawal of consent (3), Ischaemic heart disease (1) and other causes (1)."
Comment: 68/73 participants in the intervention group 1 (epoetin alpha to achieve HB of 9.5‐10.5 g/dL) and 66/73 participants in the intervention group 2 (epoetin alpha to achieve Hb of 13‐14 g/dL) completed the study (> 5% lost to follow‐up, with differences between groups). Some reasons for discontinuations appeared to be related with the intervention. However, analyses were performed in 45 and 49 participants, respectively
Selective reporting (reporting bias) Low risk Information about the protocol and the statistical analysis plan were not reported. Fatigue was reported using multiple eligible outcome measurements (scales, time points). Fatigue was reported in a format that was not extractable for meta‐analysis.

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "Randomisation by means of a computer‐generated random number table (1:1) was to either the nutritional drink, or matching placebo in accordance with the minimization method with three factors (sex, age, each of four dialysis centre); one drink was taken by patients after each dialysis session under the supervision of a nurse."
Comment: Computer generation is considered as low‐risk of bias. No imbalance between intervention groups was apparent
Allocation concealment (selection bias) Unclear risk Quote: "Originally assigned code numbers were kept in closed envelopes within the coordinating centre."
Comment: It was not reported if envelopes were numbered and opaque. No imbalance between intervention groups was apparent
Blinding of participants and personnel (performance bias)
All outcomes Low risk Quote: "The patients and attending physicians were blinded to the treatment. [...] All study investigators, medical staff, statistician and participants were blinded to the randomisation procedure and treatment assignments."
Comment: A double‐blind study was considered as low risk of bias
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "The safety of the intervention and scientific integrity of the study were supervised by an independent data and safety monitoring board located at the Center for Drug & Food Clinical Evaluation, Osaka City University Hospital, Osaka, Japan (coordinating centre)."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. It was not clearly stated if the independent data and safety monitoring was blinded to the treatment assigned. However, subjective and objective outcomes were reported. It was not stated if the independent data safety and monitoring board was blinded to the treatment allocation
Incomplete outcome data (attrition bias)
All outcomes Unclear risk Quote: "172 patients (86 in each group) completed the study. [...] One participant withdrew consent before the randomisation and a total of 202 patients [Inoue Hospital, Suita, Japan (n = 72); Ohno Memorial Hospital, Osaka, Japan (n = 54); Okada Clinic, Osaka, Japan (n = 31); Shirasagi Hospital, Osaka, Japan (n = 46)] were included in the trial and were randomly assigned to one of the two treatment arms. Of the 202 participants, six in the nutritional drink group and two in the placebo group did not receive allocation. Four participants in the nutritional group and two in the placebo group did not receive allocation because they withdrew consent. Two participants in the nutritional drink group did not receive allocation because of hospitalisation or changing the time of dialysis from afternoon to morning. Ten participants in each group discontinued intervention (in the nutritional group, 4 withdrew consent and 6 experienced adverse effects; in the placebo group, 1 withdrew consent, 1 was hospitalised, 5 experienced adverse effects, 2 changed the time of dialysis from afternoon to morning, and 1 had unknown reasons). Finally, 68 patients in Inoue Hospital, 43 in Ohno Memorial Hospital, 24 in Okada Clinic, and 39 in Shirasagi hospital completed the intervention. One patient was excluded from the final analysis because of changing the hospital visit date from a weekday to the weekend."
Comment: Figure 1 reported that no patients were lost to follow‐up. However, 87/103 participants in the intervention group and 86/99 participants in the control group were analysed. 0/103 participants in the intervention group and 1/99 participants in the control group were excluded from the analyses (ITT)
Selective reporting (reporting bias) High risk Protocol was published. Fatigue was reported in accordance with a pre‐specified analysis plan, using multiple eligible outcome measurements (scales, time points). Fatigue was reported in a format that was extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Low risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding was not involved in the design, execution, analysis, or reporting of the results of this study. The study seemed to be free from other source of bias

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Unclear risk Quote: "Fifty six patients who had undergone haemodialysis and meeting the inclusion criteria, were divided into two groups by simple random sampling."
Comment: Sequence generation methods were not reported in sufficient detail to permit judgement
Allocation concealment (selection bias) Unclear risk Method of allocation concealment was not reported in sufficient detail to permit judgement
Blinding of participants and personnel (performance bias)
All outcomes High risk Quote: "This study was done as a single‐blind clinical trial. [...] TEAS group treated by acupuncture in real points, while, in the TEAS‐Sham patients, based on the acupuncture expert opinion, the procedure was implemented for them in the false points, so that the patients were not aware of their grouping and blinded about it."
Comment: A single‐blind study is considered as high risk of bias
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "The questionnaires were filled up by the researcher before and after 10th session of intervention."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant/investigators beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. It was not stated if the interviewer was blinded to the treatment allocation
Incomplete outcome data (attrition bias)
All outcomes High risk Quote: "In this study 95 patients were screened, 72 patients met the inclusion criteria and 60 patients agreed and consented to the study. Four patients were excluded over the intervention: 2 in the TEAS group and 2 in the sham group. Finally, 56 cases including 28 cases in the TEAS group and 28 cases in the Sham group completed the research."
Comment: 28/30 participants in the intervention group and 28/30 participants in the control group completed the study (> 5% lost to follow‐up, without differences between groups). Reasons for discontinuations were not reported
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan were not reported. Fatigue was reported using multiple eligible outcome measurements (scales, time points). Fatigue was reported in a format that was extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Low risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding was unlikely to influence the data analysis

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "The subjects were allocated into three groups randomly by lottery based on the days of week done. The two hospital‐based research environments were divided based on morning and afternoon shifts and even and odd days. Then, every shift, the hospital and day were assigned randomly to one of the groups: A (relaxation techniques), B (aromatherapy), or C (control group). At first, each group was assigned a number and drew, in that order, another set of numbers to determine their lottery drawing order."

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote from Georgianos 2015: "Randomization was performed using a random permuted block design, and computer‐generated random sequence was used for allocation concealment."
Comment: A computer‐generated random sequence is considered as low risk of bias. No imbalance between intervention groups was apparent
Allocation concealment (selection bias) Low risk Quote from Agarwal 2014: "Subjects were randomised in a 1:1 ratio to either atenolol or lisinopril using concealed opaque envelopes, using a random permuted block design. A permuted block design was chosen to avoid imbalance in assignment to the study drugs over time. Random sequence was generated by a statistician using a computer program and study technicians opened these envelopes after confirming eligibility with the principal investigator."
Comment: There was no reason to suspect that the statistician had knowledge of the forthcoming allocation. However, It was not reported if envelopes were numbered
Blinding of participants and personnel (performance bias)
All outcomes High risk Quote from Agarwal 2014: "The Hypertension in Hemodialysis Patients Treated with Atenolol or Lisinopril (HDPAL) was a randomised, open‐label, parallel group, active control, single‐centre trial that compared the safety and efficacy of ACE‐inhibitor‐based therapy with β‐ blocker‐based treatment, each administered three times weekly after dialysis."
Comment: An open‐label study is considered as high risk of bias
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote from Agarwal 2016: "To accurately capture the adverse effects of atenolol and lisinopril in the HDPAL trial, we used a structured questionnaire."
Quote from Agarwal 2014: "An independent data and safety monitoring board reviewed the safety data and the study progress on an annual basis."
Comment: An independent data and safety monitoring board reviewed outcomes. The outcomes were assessed with an appropriate measure, without differences between groups (fatigue was reported as an adverse event). It was not stated if the independent data and safety monitoring was blinded to the treatment assigned. However, objective and subjective outcomes were assessed. It was not stated if the interviewer was blinded to the treatment allocation to evaluate fatigue
Incomplete outcome data (attrition bias)
All outcomes High risk Quote from supplementary Figure 1 in Agaewal 2014: "Reasons for removal by PI: Four subjects refused to perform home blood pressure monitoring repeatedly, one had pain with home BP measurements and one was excluded following a stroke. Reasons for withdrawal of consent was as follows. Atenolol: not feeling well, light‐headed, BP too low, changed mind, wanted original medications, worry about BP, study medication made the subject sick Lisinopril: dizziness, headaches, high BP, fear of stroke, tired of taking BP, tired of participating (n= 4), no reason offered (n= 3), refused home BP monitoring, did not want study medication (n=2), wanted to go back on metoprolol."
Comment: As reported in Figure 1, 58/100 in the intervention group 1 (Atenolol) and 46/100 in the intervention group 2 (Lisinopril) completed the study (> 5% lost to follow‐up, with differences between groups). Some reasons for discontinuations appeared to be related with the intervention
Selective reporting (reporting bias) Low risk Protocol was published. Fatigue was reported in accordance with a pre‐specified analysis plan, using multiple eligible outcome measurements (scales, time points). Fatigue was reported in a format that was not extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were reported. Fatigue was reported but not extractable
Other bias High risk Quote from Agarwal 2014: "We terminated the trial on the unanimous recommendation of the independent data safety monitoring board which found a clear signal for cardiovascular safety on an annual monitoring meeting after complete randomisation. At their annual meeting, the committee also noted that the lisinopril group experienced an increase in the following: all‐cause serious adverse events, all‐cause hospitalisation rates, hypertension and hyperkalaemia."
Comment: There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding was unlikely to influence the data analysis and authors did not report conflicts of interest. However, the study was terminated early

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote; "Randomisation was computer‐generated in block of 4."
Comment: Computer‐generation is considered as low risk of bias. No imbalance between intervention groups was apparent
Allocation concealment (selection bias) Low risk Quote: "Assignments were made sequentially by a research pharmacist who dispensed medication but was not otherwise involved in the study."
Quote: "Esternal research pharmacist seemed to ensure allocation concealment. No imbalance between intervention groups was apparent."
Blinding of participants and personnel (performance bias)
All outcomes Low risk Quote: "Dialysis staff, patients, and investigators were blinded through the study to treatment assigned."
Comment: A double‐blind trial is considered as low risk of bias
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "Quality of life was assessed by and instrument administered by personal interview."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk Quote: "25 subjects completed the 6‐month protocol and 23 of these (12 in the nandrolone group and 11 in the placebo group) had all measurements made. Two subjects completed the study but were unable to have final measurements taken because of medical instability. Three subjects were withdrawn from the placebo group because of elevated transaminase, hematoma at the study drug injection site, ans sudden death. One subject in the nandrolone group was withdrawn after developing angina."
Comment: 12/14 participants in the intervention group and 11/15 participants in the control group completed and reported all measurements of the study (> 5% lost to follow‐up, with differences between groups). Reasons for discontinuations seemed to be related to the treatment allocation
Selective reporting (reporting bias) High risk Protocol was approved by the Committee on Human Research at the University of California. Fatigue was reported using multiple eligible outcome measurements (scales, time points). Fatigue was reported in a format that was extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Low risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding was unlikely to influence the data analysis and conflicts of interest were not reported

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "Participants were randomly assigned to treatment groups in a 1:1:1:1 manner by the research pharmacist using variable block sizes, which were not known to investigators until the completion of the study."
Comment: Sequence generation methods were not reported in sufficient detail to permit judgement. No imbalance between intervention groups was apparent
Allocation concealment (selection bias) Low risk Quote: "Nandrolone decanoate and a placebo that was identical in appearance to the active drug were prepared and supplied to the research pharmacy by Organon, Inc. (Roseland, NJ)."
Quote: "Participants were randomly assigned to treatment groups in a 1:1:1:1 manner by the research pharmacist using variable block sizes, which were not known to investigators until the completion of the study."
Comment: Esternal research pharmacist seemed to ensure allocation concealment. No imbalance between intervention groups was apparent
Blinding of participants and personnel (performance bias)
All outcomes Unclear risk Quote: "Interventions included double‐blinded weekly nandrolone decanoate (100 mg for women; 200 mg for men) or placebo injections."
Comment: Although author reported that the study used a double‐blind design, information about blinding of participants and investigators were not clearly stated
Blinding of outcome assessment (detection bias)
All outcomes High risk The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk Quote: "Eighty haemodialysis patients were enrolled in the study, and 79 were randomly assigned. [...] Sixty‐eight patients completed the study. Reasons for non completion are shown in Figure 1. Six participants discontinued study drug (four who were receiving placebo and two who were receiving nandrolone) before the end of the treatment period, only two of whom discontinued all study participation. Therefore, results for the four patients who discontinued study drug but were still available for follow‐up measures are included in analyses. Those who received placebo discontinued because of an itchy reaction at the injection site, a nonspecific feeling that the drug was having adverse effects, abdominal pain and liver function test abnormalities, and discovery of a history of prostate cancer. Those who received nandrolone discontinued because of interference with sexual function (after five doses) and fear of possible adverse effects (after three doses)."
Comment: 16/19 participants in the intervention group 1 (nandrolone), 16/20 participants in the intervention group 2 (nandrolone + lower extremity resistance exercise training), 17/20 participants in the control group 1 (placebo) and 19/20 participants in the control group 2 (placebo + lower extremity resistance exercise training) completed and reported all measurements of the study (> 5% lost to follow‐up, with differences between groups). Reasons for discontinuations seemed to be related to the treatment allocation.
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan were not reported. Fatigue was reported using multiple eligible outcome measurements (scales, time points). Fatigue at the end of treatment was not reported in a format that was extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias High risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Pharmaceutical company who provided the drugs could influenced the data analysis and authors did not report conflicts of interest

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "Patients enrolled by a research assistant assigned into the study while the order that the patients assigned to the first scenario was randomly using a computer random number generator."
Allocation concealment (selection bias) Low risk Quote: "Patients enrolled by a research assistant assigned into the study while the order that the patients assigned to the first scenario was randomly using a computer random number generator."
Comment: Although it was not clear if research assistant was aware of treatment allocation, the use of computer seemed to prevent bias in allocation concealment
Blinding of participants and personnel (performance bias)
All outcomes High risk Not reported. However, interventions were different and participants and/or investigators could be aware of the treatment assigned
Blinding of outcome assessment (detection bias)
All outcomes High risk The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. Fatigue was not clearly reported. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk 21/24 participants in the intervention group and 23/24 participants in the control group completed the study (> 5% lost to follow‐up). There were differences between groups. Reasons for discontinuation were provided
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan were reported. It was not reported if multiple eligible outcome measurements (scales and time points) were pre‐specified. It was unclear if the reported approach to analysing this outcome was pre‐specified or influenced by the results. Fatigue at the end of treatment was not reported in a format that was extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Low risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding was unlikely to influence data analysis and interpretation. No other source of bias were apparent

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "The patients were assigned to the study or control group using fifty sets of computer‐generated random numbers."
Comment: Computer generation is considered as low risk of bias. No imbalance between intervention groups was apparent
Allocation concealment (selection bias) Unclear risk Method of allocation concealment was not reported in sufficient detail to permit judgement

Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk Quote: "The 160 patients who joined the study were randomly assigned to either the study or control group. There were 80 patients in each of the treatment arms. At week 12, 69 of the 80 (86.3%) study patients and 66 of the 80 (82.5%) controls had completed the follow‐up questionnaires. A total of 135 patients completed the protocol and were included in the analysis (Figure 1)."
Comment: 69/80 participants in the intervention group and 66/80 participants in the control group completed the study (> 5% lost to follow‐up, without differences between groups). Reasons for discontinuations seemed to be not related to the treatment allocation

Comment: Although author reported that the study used a double‐blind design, information about blinding of participants and investigators were not clearly stated
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "In order to investigate the effect of the treatment methods on the patients’ quality of life, a structured interview was performed before and after the study, where the interviewer (the same person for all patients), based upon the patients answers given, calculated a score for the most common complaints that can be seen among haemodialysis patients. [...] Neither the patient, nor the interviewer, saw the results from week 0 during the week 8 interview."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely.

Intervention group
  • Epo alfa (SC): to reach normal Hb 135 to 150 g/L in females and 145 to 160 g/L in males

    • Patients randomised to N‐Hb not already receiving epoetin initially received 50 U/kg of epoetin alfa 3 times/week. For patients already receiving epoetin, the initial dose increment was 50%. The dose was increased by 25% if reticulocytes had not increased by at least 75% after 2 weeks of treatment. Epoetin alfa was increased by a further 25%, if the increase in Hb was < 10 g/L after 4 weeks. The dose was then adjusted every 2 weeks, aiming at a monthly increase in Hb of 10 to 15 g/L to reach the target Hb level within 3 months

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Unclear risk Sequence generation methods were not reported in sufficient detail to permit judgement
Allocation concealment (selection bias) Unclear risk Method of allocation concealment was not reported in sufficient detail to permit judgement
Blinding of participants and personnel (performance bias)
All outcomes High risk Quote from Furuland 2003: "This was a multicenter, randomised, open‐label trial in patients with renal anaemia."
Comment: An open‐label study is considered as high risk of bias
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote from Furuland 2003: "Thrombovascular events and vascular access thrombosis were recorded and categorized centrally by one coordinator based on a WHO classification."
Comment: Some outcomes were recorded centrally (not sure that it was valid also for fatigue). The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk As reported in table 2, overall 73/180 participants in the intervention group and 83/164 participants in the control group completed the study (> 5% lost to follow‐up, with differences between groups). Some reasons for discontinuations (adverse events) seemed to be related to the treatment allocation
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan were not reported. Fatigue was reported using multiple eligible outcome measurements (scales, time points). Fatigue was reported in a format that was extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Unclear risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding and conflicts of interest were not reported

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "Randomization was performed by MedCalc software to give equal chance to each intervention group."
Comment: Computer‐generation is considered as low risk of bias. No imbalance between intervention groups was apparent
Allocation concealment (selection bias) Unclear risk Method of allocation concealment was not reported in sufficient detail to permit judgement
Blinding of participants and personnel (performance bias)
All outcomes High risk Not reported. However, interventions were different and participants and/or investigators could be aware of the treatment assigned
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "The data of the intervention and control groups were collected by using the questionnaire, Piper Fatigue Scale and Visual Analogue Scale (VAS)."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk The number of patients who completed the study was not clearly stated. It was unclear if there was evidence that the results were not biased by missing outcome data
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan were not reported. Fatigue was reported using multiple eligible outcome measurements (scales, time points). Fatigue was reported in a format that was extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Unclear risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding and conflicts of interest were not reported

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote from Foley 2008: "The study was centrally coordinated from St. John’s, Canada for Canadian patients and Manchester, England for European patients. Randomization was performed at the coordinating centres with an interactive voice randomisation telephone system using permuted blocks stratified by concurrent epoetin use and sex."
Comment: The interactive voice system is likely to be a computer. No imbalance between intervention groups was apparent
Allocation concealment (selection bias) Low risk Quote from Foley 2008: "The study was centrally coordinated from St. John’s, Canada for Canadian patients and Manchester, England for European patients. Randomization was performed at the coordinating centres with an interactive voice randomisation telephone system using permuted blocks stratified by concurrent epoetin use and sex."
Comment: An interactive voice system is considered as low risk of bias. No imbalance between intervention groups was apparent
Blinding of participants and personnel (performance bias)
All outcomes Low risk Quote from Foley 2009: "Patients and attending physicians were masked to treatment assignment. [...] Local investigators and the dialysis unit were also masked to treatment assignment."
Quote from Parfley 2005: "A randomised, double‐blind design was used with patients and outcome assessors but not treating physicians, who were blinded to assigned haemoglobin target."
Comment: A double‐blind trial is considered as low risk of bias
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote from Foley 2009: "Quality of life was assessed using the KDQoL questionnaire, with prespecified outcomes being Energy/Fatigue scores, and Quality of Social Interaction Scores."
Quote from Foley 2009: "Independent Data Monitoring Committee Members."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting (not sure that the Independent Data Monitoring Committee Members assessed fatigue). Participant/investigators beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. It was not stated if the independent data monitoring was blinded to the treatment assigned. However, objective and subjective outcomes were assessed. It was not stated if the interviewer was blinded to the treatment allocation
Incomplete outcome data (attrition bias)
All outcomes Unclear risk Quote from Parfley 2005: "324 (54%) patients remained in the study for 96 weeks, 160 (54%) in the higher and 164 (55%) in the lower target groups. The reasons for study exit— renal transplantation (n 133, 67 in the higher and 66 in the lower target group), adverse events (n 76, 39 and 37), patient choice (n 28, 9 and 19), loss to follow‐up (n 2, 1 and 1), and other (n 36, 21 and 15)—were similar in the two target groups."
Comment: 164/300 participants in intervention group 1 (epoetin alfa to reach low target haemoglobin) and 160/296 participants in intervention group 2 (epoetin alfa to reach high target Hb) completed the study (> 5% lost to follow‐up, without differences between groups). Reasons for discontinuations (adverse events) seemed to be related to the treatment allocation. However, all outcomes have been reported on the ITT population
Selective reporting (reporting bias) Low risk Information about the protocol and the statistical analysis plan were not reported. Fatigue was reported using multiple eligible outcome measurements (scales, time points). Fatigue was reported in a format that was extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were reported
Other bias High risk Quote from Foley 2009: "Baseline characteristics were similar except for the older age of high target subjects (52.2 versus 49.4 years)."
Comment: There was no substantial evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding (pharmaceutical company) could influence the data analysis and authors reported conflicts of interest

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote from Greenword 2020: "Randomization was conducted via a centrally controlled web based randomisation system, run by the Glasgow Clinical Trials Unit (GCTU). To ensure balanced assignment across critical variables, a minimization algorithm was employed, taking into account baseline age, gender and diabetes status."
Allocation concealment (selection bias) Unclear risk Method of allocation concealment was not reported in sufficient detail to permit judgement
Blinding of participants and personnel (performance bias)
All outcomes High risk Quote from Greenword 2020: " It was impossible to blind the ‘treating’ physiotherapy assistants or the participants, and thus the study implemented a blinded outcome assessment and analysis."
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote from Greenword 2020: "This was a prospective, pragmatic multicenter RCT with blinded outcome assessment."
Fatigue was assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk Quote from Greenword 2021: "In total, the trial recruited 379 participants. A total of 335 participants attended a baseline study visit: 175 participants who were randomised to the exercise intervention and 160 participants who were randomised to usual care. Participants were informed of group allocation only after completing all baseline assessments. Fifty‐nine patients allocated to the exercise intervention and 60 participants allocated to usual care did not complete the 6‐month assessment. In total, seven participants died during the study: three participants from the intervention group and four participants from the usual‐care group. In the intervention group, 40 participants were withdrawn and 16 did not attend for the final 6‐month assessment. In the usual‐care group, 15 participants were withdrawn and 14 participants did not attend the 6‐month assessment."
Comment: 116/175 participants in the intervention group and 127/160 participants in the control group (no intervention) completed the study (> 5% lost to follow‐up, with differences between groups). Reasons for discontinuations were reported
Selective reporting (reporting bias) Low risk Protocol was published. Fatigue was reported in accordance with a pre‐specified analysis plan, using multiple eligible outcome measurements (scales, time points). Fatigue was reported in a format that was extractable for meta‐analysis. However, objective and subjective outcomes were assessed. All outcomes that should be addressed (fatigue, CVD, and death) were reported
Other bias Low risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding was unlikely to influence the data analysis and authors had no conflicts of interest. The study seemed to be free from other source of bias

Random sequence generation (selection bias) Low risk Quote: "Randomisation was stratified by centre and randomly varying block sizes were used to maintain balance of numbers in each arm across the period of recruitment while maintaining allocation concealment.

Blinding of participants and personnel (performance bias)
All outcomes High risk Quote: "The nature of the trial meant participants were unblinded to their allocations."
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "Follow‐up measures were completed independently by participants via post. An independent researcher, who was not involved in the intervention development or delivery, assisted seven participants with the completion of the follow‐up measures. The statistician (SN) remained blind to treatment allocation until after the analyses were conducted."
Comment: Fatigue was assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, objective and subjective outcomes were assessed. It was not stated if the interviewer was blinded to the treatment allocation

Selective reporting (reporting bias) High risk Information about the protocol were reported. It was not reported if multiple eligible outcome measurements (scales and time points) were pre‐specified. It was unclear if the reported approach to analysing this outcome was pre‐specified or influenced by the results. Fatigue at the end of intervention was reported in a format that was not extractable for meta‐analysis.

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Unclear risk Sequence generation methods were not reported in sufficient detail to permit judgement
Allocation concealment (selection bias) Unclear risk Method of allocation concealment was not reported in sufficient detail to permit judgement
Blinding of participants and personnel (performance bias)
All outcomes High risk Quote: "Chronic haemodialysis patients participated in this randomised, single masked, controlled crossover trial. [...] Throughout the entire study, patients were masked to dialysate glucose levels"
Comment: A single‐blind study is considered as high risk of bias
Blinding of outcome assessment (detection bias)
All outcomes High risk The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes Low risk All participants completed the study. No patients were loss to follow‐up
Selective reporting (reporting bias) High risk The study protocol was approved by the Institutional Review Board of Beth Israel Medical Center. It was not reported if multiple eligible outcome measurements (scales and time points) were pre‐specified. It was unclear if the reported approach to analysing this outcome was pre‐specified or influenced by the results. Fatigue at the end of treatment was not reported in a format that was extractable for meta‐analysis (cross‐over study: data related to the first period were not reported). All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Unclear risk No data were available to assess the possible imbalance between groups. There was no funding and the authors did not have conflicts of interest

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote from Reilly‐Sponge 2015: "Randomisation schedules were computer‐generated using SAS, and designed using small randomly permuted blocks to promote balance within strata across treatment arms."
Comment: Computer‐generated is considered as low risk of bias
Allocation concealment (selection bias) Low risk Quote from Reilly‐Sponge 2015: "The randomisation schedule was generated by the study statistician who was masked with respect to variables other than stratification variables."
Comment: The statistician should ensure concealment and it was assessed as low risk of bias
Blinding of participants and personnel (performance bias)
All outcomes High risk Quote from Gross 2017: "We conducted a randomised, active‐controlled, open‐label trial to test whether a Mindfulness‐based Stress Reduction (MBSR) program delivered in a novel workshop‐teleconference format would reduce symptoms and improve health‐related quality of life in patients awaiting kidney transplantation."
Comment: An open‐label study is considered as high risk of bias
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote from Gross 2017: "Participants completed self‐report questionnaires at baseline, post‐intervention, and after 6‐months."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk The number of patients who completed the study with GFR < 15 mL/min/1.73 m2 was not clearly stated. It was unclear if there was evidence that the results were not biased by missing outcome data
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan were reported. It was not reported if multiple eligible outcome measurements (scales and time points) were pre‐specified. It was unclear if the reported approach to analysing this outcome was pre‐specified or influenced by the results. Fatigue at the end of treatment was reported in a format that was not extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Low risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding was unlikely to influence the data analysis and reporting and authors had no conflicts of interest

  • Indication: study targeting fatigue


Intervention group 1
  • Protocol A: standard dialysis (steady dialysate sodium of 140 mEq/L)


Intervention group 2
  • Protocol B: linear sodium ramping during dialysis (initial dialysate sodium of 155 mEq/L, continuous decline to 140 mEq/L by the end of the dialysis)


Intervention group 3
  • Protocol C: stepwise ramping sodium (dialysate sodium of 155 mEq/L for the first 3 hours and 140 mEq/L for the last hour of dialysis)


Cointerventions
  • All patients underwent 4‐hour HD with the blood flow set to achieve an approximate Kt/V of 1.4

  • All dialyses were performed with hollow‐fibre cellulose membrane filters, bicarbonate dialysate, and systemic heparin

Outcomes Outcomes reported
  • Fatigue outcome measures used: validation data available

  • Adverse events (including hypertension and fatigue)

    • Questionnaire: patients rated thirst, cramps, and headaches from a scale of 1 = absent to 5 = severe. Each symptom could thus score between 0 and 30 for a 2‐week period. Fatigue was scored as present or absent. The sum of each side effect was calculated and compared for each 2‐week period and separately for the 12 hours immediately following the dialysis session as well as the next day

  • Vital signs (SBP, DBP, pulse rate): assessed every hour

  • Interrdialitic weight gain: assessed during each treatment

  • Laboratory results: sodium, urea, creatinine, and HCT levels were monitored weekly, both before and after the dialysis, and albumin, calcium, potassium, and phosphate levels were examined before dialysis each week

  • Total ultrafiltration: the timeframe of this outcome was not clearly reported, it was probably assessed during each treatment

  • Assessment of dialysis

    • Analogue scale questionnaire (1 = the worst, intolerable dialysis and 5 = excellent dialysis, with 3 being a normal dialysis session): immediately after the dialysis session, the mean score for each 2‐week period was calculated

[...] There were eight protocol violations; two occurred during standard haemodialysis, one during linear ramping, and five during stepwise ramping. Data for the eight haemodialysis sessions were excluded in the analysis."
Comment: Authors reported that patients were blinded. However, interventions were different and investigators could be aware of the treatment assigned

[...] Six patients stopped their treatments because of thirst. When they stopped, they were evenly distributed with two in each protocol."
Comment: Overall, 23/29 participants completed the study (> 5% lost to follow‐up, difference between groups could not be assessed). Reasons for discontinuations seemed to be related to the treatment allocation
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan were not reported. It was not reported if multiple eligible outcome measurements (scales and time points) were pre‐specified. It was unclear if the reported approach to analysing this outcome was pre‐specified or influenced by the results. Fatigue at the end of treatment was not reported in a format that was extractable for meta‐analysis.

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "Randomization occurred through the www.random.org website."
Allocation concealment (selection bias) Low risk Quote: "The sequence of numbers was generated by a researcher “blinded” to the study, and it was kept confidential until the beginning of the intervention to guarantee the concealment of the allocation."
Blinding of participants and personnel (performance bias)
All outcomes High risk Not reported. However, interventions were different and participants and/or investigators could be aware of the treatment assigned
Blinding of outcome assessment (detection bias)
All outcomes Low risk Quote: "All analyses were conducted by a researcher blind to the study procedures (randomisation, evaluations, and intervention)."
Comment: Fatigue was assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, subjective and objective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk Quote: "Thirty‐six patients with CKF on HD were evaluated for eligibility and possible admission into the study. Twenty‐eight met the inclusion criteria and finalized the protocol."
Comment: 14/17 participants in the intervention group and 14/16 participants in the control group completed the study (> 5% lost to follow‐up). There were differences between groups. Reasons for discontinuation were reported
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan were reported. Fatigue was assessed using multiple eligible outcome measurements (scales and time points). Fatigue at the end of treatment was reported in a format that was not extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Low risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding was unlikely to influence data analysis and interpretation. No other source of bias were apparent

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "Each patient was treated for 4 weeks with standard dialysate (standard phase) and 4 weeks with citrate dialysate (citrate phase) in the sequence determined by the computer‐generated randomisation scheme. A centralized fax randomisation in a 1:1 ratio with stratification for centre and dialysis modality was carried out."
Comment: A computer‐generated randomisation scheme is considered as low risk of bias. No data were available to assess the possible imbalance between groups
Allocation concealment (selection bias) Unclear risk Method of allocation concealment was not reported in sufficient detail to permit judgement
Blinding of participants and personnel (performance bias)
All outcomes High risk Not reported. However, interventions were different and investigators could be aware of the treatment assigned
Blinding of outcome assessment (detection bias)
All outcomes High risk The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used (fatigue was assessed as an adverse event), it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk Quote: "Of the 95 patients enrolled (HDF post‐dilution: 44, HDF pre‐dilution: 26, HD: 25), 7 terminated the study prematurely for reasons not associated with the study protocol, e.g. kidney transplantation or death due to an exacerbation of concomitant diseases. Three of them were completely excluded from the analysis because they were withdrawn before the first study treatment, so the full analysis set (FAS) constituted of 92 patients."
Comment: Overall, 92/95 participants were reported in the analysis. However, Figure 1 showed that only 48/95 participants were assessed per protocol analysis. Tables 2, 3 and 5 reported data for 90 participants in the standard dialysate phase
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan were reported. It was not reported if multiple eligible outcome measurements (scales and time points) were pre‐specified. It was unclear if the reported approach to analysing this outcome was pre‐specified or influenced by the results. Fatigue at the end of treatment was not reported in a format that was extractable for meta‐analysis (cross‐over study: data related to the first period were not clearly reported). All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "Randomisation was by computer‐generated random number with subjects stratified according to diabetic status and by the need for maintenance dialysis treatment."
Comment: A computer‐generated randomisation scheme is considered as low risk of bias
Allocation concealment (selection bias) Low risk Quote: "Study drugs were compounded and packaged by an external pharmacy."
Comment: External pharmacy performed the allocation concealment
Blinding of participants and personnel (performance bias)
All outcomes Low risk Quote: "The study design was a prospective, single‐centre, double‐blind, randomised, placebo‐controlled trial. [...] Both the subjects and investigators were blinded as to allocation until after the final subject had completed the study, and all follow‐up data had been collected."
Comment: A double‐blind trial is considered as low risk of bias
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote; "The Kidney Dialysis Quality of Life‐Short Form (KDQOL‐SF) symptom and cognitive sub scales were administered either face to face or by telephone by a single research assistant."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. However, objective and subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk Quote: "Baseline ascorbate levels were not available in three subjects. This was due to mishandling of the samples in two subjects and one subject refusing venesection. A further one subject withdrew from the study after randomisation and collection of an ascorbate level, but before completing other baseline data. Data for all subjects were included until their exit from the study."
Comment: As reported in Figure 1, 48/49 participants in the intervention group and 48/51 participants in the control group completed the follow‐up period. 49/49 participants in the intervention group and 49/51 participants in the control group completed the analysis. However, data on participants undergoing dialysis were not reported in sufficient detail to permit judgment
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan were reported. It was not reported if multiple eligible outcome measurements (scales and time points) were pre‐specified. It was unclear if the reported approach to analysing this outcome was pre‐specified or influenced by the results. Fatigue at the end of treatment was not reported in a format that was extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Low risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding was unlikely to influence the data analysis and authors did not have conflicts of interest

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "Eligible patients were randomly assigned in a 1:1 ratio (simple block randomisation) to either ferumoxytol or placebo by using a telephone‐based system (ClinPhone Interactive Voice Response System, East Windsor, NJ)."
Comment: The interactive voice systems could be considered as a computer
Allocation concealment (selection bias) Low risk Quote: "Eligible patients were randomly assigned in a 1:1 ratio (simple block randomisation) to either ferumoxytol or placebo by using a telephone‐based system (ClinPhone Interactive Voice Response System, East Windsor, NJ)."
Comment: Interactive system voice is considering as low risk of bias
Blinding of participants and personnel (performance bias)
All outcomes Low risk Quote: "Patients, investigators, and study coordinators were blinded, with the exception of 1 individual at each site designated the Test Article Administrator, who administered study treatments."
Comment: A double‐blind trial is considered as low risk of bias
Blinding of outcome assessment (detection bias)
All outcomes Low risk Quote: "The blinded investigators and study coordinators, but not the Test Article Administrator, were involved in the assessment and attribution of adverse events. [...] All laboratory tests were performed at a central laboratory. [...] Relatedness of AEs to treatment was determined by the blinded site investigators. [...] Direct questioning of study patients regarding adverse events."
Comment: Blinded investigators and study coordinators were involved in the assessment and attribution of adverse events (including fatigue)
Incomplete outcome data (attrition bias)
All outcomes High risk The number of patients who completed the study was not clearly stated. It was unclear if there was evidence that the results were not biased by missing outcome data
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan were reported. It was not reported if multiple eligible outcome measurements (scales and time points) were pre‐specified. It was unclear if the reported approach to analysing this outcome was pre‐specified or influenced by the results. Fatigue at the end of treatment was not reported in a format that was extractable for meta‐analysis (cross‐over study: data related to the first period were not clearly reported). All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias High risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Government funding was unlikely to influence the data analysis but the pharmaceutical company could influence the data analysis and authors had conflicts of interest

Blinding of participants and personnel (performance bias)
All outcomes High risk Quote: "Patients were blinded with respect to the type of membrane used during all dialysis treatments throughout the study."
Comment: Not reported if investigators were blind. However, interventions were different and investigators could be aware of the treatment assigned
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "Levels of post dialysis fatigue were determined by analysis of 6‐hour logs of sleep and perception of fatigue recorded by patients after each of these dialysis treatments. At the completion of the study, the patients submitted their log sheets to one of the investigators."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. Other objective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk Quote: "Five patients were not included in the data analysis because they were individuals who destabilized medically (2) or submitted incomplete log sheets (3)."
Comment: Overall, 16/21 participants completed the study (> 5% lost to follow‐up, difference between groups could not be assessed). Reasons for discontinuations seemed to be not related to the treatment allocation

  • Fatigue was addressed by therapist: it was reported "Although there is currently no standardized outcome measure for fatigue in HD patients, approaches such as our study, which address both the person and their environment, might offer a means to meaningfully reduce symptoms. Energyconservation techniques, such as those taught by our occupational therapist, might be particularly impact for HD patients."

All outcomes High risk Quote: "The EMS group included 14 men and 1 woman, while the control group included 13 men and 1 woman. Thirteen (86.7%) participants in the EMS group completed EMS training. The reasons for failure to complete training were hospitalisation before intervention (n51) and dropout due to discomfort of the wet electrode bands (n51). Likewise, 13 (92.9%) participants in the control group completed the protocol. One participant in the control group withdrew consent to join the study. The final analyses included 13 patients in each group."
Comment: 13/15 participants in the intervention group and 13/14 participants in the control group completed the study (> 5% lost to follow‐up, with difference between group). Reasons for discontinuations were reported
Selective reporting (reporting bias) High risk Information about the protocol were reported. Vitality was reported using multiple eligible outcome measurements (scales, time points). Vitality was reported in a format that was extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Low risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding was unlikely to influence the data analysis and authors did not have conflicts of interest. No other source of bias were apparent

  • Abstract

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "The randomisation takes place, on a state‐by‐state basis using the method of minimisation as they agree to participate. The randomisation was stratified based upon location (state), metropolitan or regional, private or public unit or prior or current use of the IPOS‐Renal questionnaire for symptom monitoring within each centre and cluster size."
Allocation concealment (selection bias) Low risk Quote: "The trial statistician concealed until the site initiation visit. Access to the allocations is limited to the CI (RLM), the trial statistician (CB), the CTC trial operations coordinator (PW) and ANZDATA Registry Manager (Ms. Kylie Hurst) to minimise risk of inadvertently influencing sites or prematurely revealing allocation."
Blinding of participants and personnel (performance bias)
All outcomes High risk Quote: "Blinding to allocation is not possible within clusters due to the nature of the intervention; however, all staff compiling and analysing outcome data will be blinded to allocation."
Comment: Interventions were different and participants and/or investigators could be aware of the treatment assigned
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "Blinding to allocation is not possible within clusters due to the nature of the intervention; however, all staff compiling and analysing outcome data will be blinded to allocation."
Comment: Fatigue was assessed with an appropriate measure. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. Other subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk Not reported in sufficient detail to perform adjudication
Selective reporting (reporting bias) High risk Information about the protocol were reported. It was not reported if multiple eligible outcome measurements (scales and time points) were pre‐specified. It was unclear if the reported approach to analysing this outcome was pre‐specified or influenced by the results. Fatigue at the end of treatment was reported in a format that was not extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Unclear risk Quote: "The study sponsor and the study founders (Australian NHMRC, Kidney Health Australia), did not have any role or ultimate authority in study design; collection, management, analysis, interpretation of data, writing of the report, or the decision to submit the report for publication."
Comment: Baseline characteristics were not reported. Funding did not influence the data analysis and authors did not have conflicts of interest

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "The interventionists randomised the participant codes to the intervention group or the control group, using a simple 1:1 computer‐generated sequence."
Comment: A computer‐generated sequence is considered as low risk of bias. No imbalance between intervention groups was apparent
Allocation concealment (selection bias) Unclear risk Method of allocation concealment was not reported in sufficient detail to permit judgement
Blinding of participants and personnel (performance bias)
All outcomes High risk Not reported. However, interventions were different and investigators/participants could be aware of the treatment assigned
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "Participants completed questionnaires with an independent assessor who then assigned each of them an anonymous code.The interventionists, who were not involved in the recruitment process and patient assessment, randomised the participant codes to the intervention group or the control group, using a simple 1:1 computer‐generated sequence." [...] "This study was a randomised, controlled, assessor‐blinded trial conducted in an urban haemodialysis unit. Both the assessor and the statistical associate were blinded to randomisation allocation."
Comment: Fatigue was assessed as an adverse event. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. Other subjective outcomes were assessed. Not sure if the outcome assessment was blinded
Incomplete outcome data (attrition bias)
All outcomes High risk Quote: "Of missed sessions, 55% were due to logistic issues (switches in the location or time of assigned haemodialysis shifts) and 45% were due to refusals (most common reasons given were “too tired” or “too ill” on the given day). Five patients dropped out early in treatment (<2 sessions) for “feeling too medically ill” (n=1), “feeling already improved” (n=1), and “lack of interest” (n=3). One patient stopped after five sessions when they were transferred to home peritoneal dialysis therapy."
Comment: 17/21 participants in the intervention group and 15/20 participants in the control group participants completed the study (> 5% lost to follow‐up, with difference between groups). Reasons for discontinuations seemed to be not related to the treatment allocation
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan were reported. It was not reported if multiple eligible outcome measurements (scales and time points) were pre‐specified. It was unclear if the reported approach to analysing this outcome was pre‐specified or influenced by the results. Fatigue at the end of treatment was not reported in a format that was extractable for meta‐analysis.

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote from Tsai 2016: "Participants were randomly and equally allocated to either the herbal acupoint therapy (HAT) or placebo group by computer‐generated randomisation."
Quote from Tsai 2016 protocol: "Randomisation will be generated by a computerised random number function in Microsoft Excel, and the patients, programme assessors and statisticians will be unaware of the group to which they have been assigned. A block randomisation procedure (based on age, comorbidities such as cardiovascular disease and diabetes mellitus) will be employed to ensure that group allocation is equal and that the characteristics of the trial participants are similar."
Comment: A computer‐generated sequence with random numbers is considered as low risk of bias. No imbalance between intervention groups was apparent
Allocation concealment (selection bias) Unclear risk Method of allocation concealment was not reported in sufficient detail to permit judgement.
Blinding of participants and personnel (performance bias)
All outcomes Low risk Quote from Tsai 2016: "All patients, program assessors, outcome assessors, and statisticians were blind to the group allocations until the end of the clinical trial."
Comment: A double blind study is considered as low risk of bias
Blinding of outcome assessment (detection bias)
All outcomes Low risk Quote from Tsai 2016: "Patient subjective assessments of the degree of fatigue and recovery time from fatigue after dialysis in both groups. [...] All patients, program assessors, outcome assessors, and statisticians were blind to the group allocations until the end of the clinical trial."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was stated that outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment that may have influenced reporting. However, objective and subjective outcomes were assessed. Overall the outcome assessment was blinded
Incomplete outcome data (attrition bias)
All outcomes High risk Quote from Tsai 2016: "In all, 27 patients (84%) completed the entire study. [...] These patients were randomly divided into a group receiving HAT therapy (18 patients) and a group receiving sham‐HAT therapy (14 patients), and 5 patients (15.6%) dropped out before week 2. The remainder of the patients provided complete data at follow‐up."
Comment: As reported in Figure 1, 14/18 participants in the intervention group and 13/14 participants in the control group participants completed the study (> 5% lost to follow‐up, with difference between groups). Reasons for discontinuations seemed to be not related to the treatment allocation (discontinuation for disease progression and withdrawal in the intervention group and withdrawal in the control group
Selective reporting (reporting bias) High risk Protocol was published and approved by the Institutional Review Board of Chang Gung Memorial Hospital. Fatigue was reported in accordance with a pre‐specified analysis plan, using multiple eligible outcome measurements (scales, time points). Fatigue was reported in a format that was extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Low risk There was no evidence of different baseline characteristics, or different non‐randomised co‐interventions between groups. Funding was unlikely to influence the data analysis and authors did not have conflicts of interest. The study seemed to be free from other sources of bias

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Unclear risk Sequence generation methods were not reported in sufficient detail to permit judgement
Allocation concealment (selection bias) Unclear risk Method of allocation concealment was not reported in sufficient detail to permit judgement
Blinding of participants and personnel (performance bias)
All outcomes High risk Not reported. However, interventions were different and participants and/or investigators could be aware of the treatment assigned
Blinding of outcome assessment (detection bias)
All outcomes High risk Quote: "The Visual Analogue Scale (VAS) for Fatigue and the Pittsburg Sleep Quality Index (PSQI) were administered to the patients as a pretest immediately before they were taken to haemodialysis."
Comment: The outcomes were assessed with an appropriate measure, without differences between groups. However, subjective measures were used, it was not stated whether outcomes were assessed without knowledge of treatment allocation, and knowledge of treatment assignment may have influenced reporting. Participant beliefs about the superiority/inferiority of either intervention could have influenced their assessment of the outcome, but there was no evidence that this was likely. Other subjective outcomes were assessed
Incomplete outcome data (attrition bias)
All outcomes High risk Quote: "From the 110 patients, a total of 105 patients (35 patients per group) reached the end of the study, with one patient in the foot reflexology group and two patients in the back massage group having withdrawn from the study, and two patients in the control group having left the dialysis centre."
Comment: 35/36 participants in the intervention group 1 (foot reflexology), 35/37 participants in the intervention group 2 (back massage) and 35/37 participants in the control group (control) completed the study (> 5% lost to follow‐up, with difference between groups)
Selective reporting (reporting bias) High risk Information about the protocol and the statistical analysis plan were not reported. Fatigue was reported using multiple eligible outcome measurements (scales, time points). Fatigue was reported in a format that was extractable for meta‐analysis. All outcomes that should be addressed (fatigue, cardiovascular disease, and death) were not reported
Other bias Low risk There was no evidence of difference in the baseline characteristics, or different non‐randomised co‐interventions between groups. Funding was unlikely to influence the data analysis and authors had no conflicts of interest. The study seemed to be free from other sources of bias

Differences between protocol and review

We have clarified our objectives as follows: "This review aims to evaluate the effects of any pharmacological and non‐pharmacological interventions on fatigue in people with chronic kidney disease requiring dialysis, such as haemodialysis and peritoneal dialysis, including any setting (e.g. dialysis performed in the clinic or at home) and frequency."

We have clarified the inclusion criteria of the population of interest as follows: "Patients of any age with ESKD on any form of dialysis. The dialysis treatment could be performed both in the clinic and at home. Any frequency of the dialysis treatment was included."

We have clarified our interventions as follows: "We considered any intervention affecting levels of self‐reported fatigue in patients on dialysis." In addition, we have added hypoxia‐inducible factors in the type of pharmacological interventions.

We have added sleep and mood to the secondary outcomes.
