Gonzalez‐Espinoza 2005.

Methods Randomised controlled trial. 
 Duration 6 months.
Participants Adults receiving continuous peritoneal dialysis (n = 30) (19 males and 9 females in final study group). Mean (SD) age dietary advice group 47.6 (17.4) years and mean (SD) age dietary advice and supplements group 45.7 (14.4) years.
All patients malnourished according to SGA.
2 patients not included in the analysis from the dietary advice and supplements group because of deterioration in health.
Interventions Nutrtional counselling plus a dried egg‐albumin‐based supplement added to milk or sprinkled on food (n = 13) versus nutritional counselling (n = 15).
Outcomes Survival, weight*, energy intake* BMI, MAMC*, TSF* hospital admission

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Random numbers table.
Allocation concealment (selection bias) Low risk Performed by a person external to the study once the patient had provided informed consent.
Blinding (performance bias and detection bias) 
 Clinical outcomes Low risk Information from author, outcomes assessed blinded to intervention.
Blinding (performance bias and detection bias) 
 Functional outcomes Low risk Information from author, outcomes assessed blinded to intervention.
Blinding (performance bias and detection bias) 
 Nutritional outcomes Low risk Information from author, outcomes assessed blinded to intervention.
Incomplete outcome data (attrition bias) 
 All outcomes Low risk 2 patients not included in the analysis from the dietary advice and supplements group because of deterioration in health.
Selective reporting (reporting bias) Low risk All outcomes reported but not in a format suitable for entry into meta‐analysis. Data on change in weight, energy intake, TSF and MAMC are presented as mean (SD) at baseline and at end of intervention. Data on mean change (SD) from baseline were obtained from the authors for weight, energy and MAMC. SDs for change in TSF were imputed. Data on hospital admissions obtained from the authors.
Other bias Low risk Baseline characteristics reported.
