Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Quote: "Eligible participants were randomly assigned using a computer‐generated random allocation sequence"
Allocation concealment (selection bias)	Unclear risk	No information provided
Blinding of participants and personnel (performance bias) All outcomes	High risk	Quote: "Participants were not blinded to group status"
Blinding of outcome assessment (detection bias) All outcomes	High risk	Quote: "Therapists were not blind to group status"
Incomplete outcome data (attrition bias) All outcomes	Low risk	Less than 20% of participants abandoned the study prematurely Study endpoint: 2/13 missing from IPT group; 1/9 missing from WL group
Selective reporting (reporting bias)	Low risk	The study protocol is not available, but it is clear that published reports include all expected outcomes
Therapist qualification	Unclear risk	Quote: "Sudanese mental health professionals were not available in Cairo, so community members without previous mental health education were trained to deliver the care"
Treatment fidelity	Unclear risk	No information provided
Therapist/investigator allegiance	Unclear risk	No information provided
Other bias	Unclear risk	Sponsorship bias cannot be ruled out
