GRADE Working Group grades of evidence.High certainty: we are very confident that the true effect lies close to that of the estimate of the effect.
Moderate certainty: we are moderately confident in the effect estimate: the true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different.
Low certainty: our confidence in the effect estimate is limited: the true effect may be substantially different from the estimate of the effect.
Very low certainty: we have very little confidence in the effect estimate: the true effect is likely to be substantially different from the estimate of effect.

aLi 2002. Community rehabilitation (medications, counselling, requested work or social activities) vs inpatient care for patients with first episode of late‐onset schizophrenia.

bDowngraded by one level for risk of bias: high risk of selection (lack of allocation concealment) and detection (lack of blinding of outcome assessors) bias. Downgraded by one level for indirectness: the only study in this analysis was conducted in a lower‐middle‐income country, on people age 50 and older experiencing their first episode of illness (schizophrenia); intervention comprised antipsychotics and weekly home visits. Study population, setting, and intervention are not generalisable to all patients with serious mental disorders in LMICs. Downgraded by one level for imprecision: small event numbers.

cTan 2005. Community observation (medications, symptom monitoring, psychoeducation, rehabilitation) vs hospitalisation as needed for patients with schizophrenia.

dLing 1999. Family intervention (education on medication side effects and adherence, symptom monitoring, psychoeducation, counselling, family communication training) vs community psychiatric nurse‐led care for patients with schizophrenia.

eWu 2016. Self‐care model combined with collaborative care (medications, counselling, family communication training, requested work or social activities, self‐care training) vs community psychiatric nurse‐led care for patients with chronic stable schizophrenia.

fDowngraded by one level for risk of bias: high risk of detection bias (lack of blinding in outcome assessments) in all four studies, and selection bias (lack of allocation concealment) in one study (Li 2002). Downgraded by one level for indirectness: only one country represented among these studies. Downgraded by one level for imprecision: Small total event numbers.

gYao 2014. Community day rehabilitation (medications, symptom monitoring, psychoeducation, counselling, social skills training, rehabilitation) vs community psychiatric nurse‐led care for patients with chronic stable schizophrenia.

hBarfar 2017. Aftercare service (medications, education on medication side effects and adherence, symptom monitoring, psychoeducation, telephone reminders to attend outpatient clinics, social skills training) vs usual specialist care in outpatient clinics or inpatient services for patients with schizophrenia, bipolar disorder, or schizoaffective disorder.

iMalakouti 2015. Home visits by nurse or GP (medications, education on medication side effects and adherence, symptom monitoring, psychoeducation) vs usual specialist‐led outpatient clinic or hospitalisation during exacerbation for patients with schizophrenia or bipolar disorder with difficult‐to‐treat disease.

jDowngraded by one level for risk of bias: high risk of detection bias (lack of blinding in outcome assessments) in four studies (Barfar 2017Li 2002Ling 1999Tan 2005), selection bias (lack of allocation concealment) in one study (Li 2002), and attrition bias in one study (Malakouti 2015). Downgraded by one level for inconsistency: large unexplained statistical heterogeneity (I² = 87%). Downgraded by one level for imprecision: confidence level of SMD ranges from moderate clinical effect favouring PHP‐led or collaborative care to no clinical effect. Note that a small clinically appreciable benefit was set at SMD 0.2 to 0.5, a moderate benefit at SMD 0.5 to 0.8, and a large benefit at > 0.8 (Cohen 1988).

kDowngraded by one level for risk of bias: high risk of detection bias in Barfar 2017 and Ling 1999. Downgraded by one level for inconsistency: large unexplained statistical heterogeneity (I² = 89%). Downgraded by one level for imprecision: low total number. Confidence interval of SMD ranged from favouring PHP‐led or collaborative care to favouring specialist‐led care.

lDowngraded by one level for risk of bias: high risk of detection bias in Barfar 2017 and Wu 2016, and attrition bias in Malakouti 2015. Downgraded by one level for inconsistency: large unexplained statistical heterogeneity (I² = 94%). Downgraded by one level for imprecision: confidence interval of effect size ranges from large clinical effect favouring PHP‐led or collaborative care to favouring specialist‐led care.

mDowngraded by one level for risk of bias: high risk of detection bias (lack of blinding in outcome assessments) in five studies (Barfar 2017Li 2002Ling 1999Tan 2005Wu 2016), selection bias (lack of allocation concealment) in one study (Li 2002), and attrition bias in one study (Malakouti 2015). Downgraded by one level for inconsistency: large unexplained statistical heterogeneity (I² = 95%).

nDowngraded by one level for risk of bias: high risk of detection bias in Barfar 2017 and Wu 2016, and attrition bias in Malakouti 2015.
