Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Quote: "following the structured interview a code was broken and they were assigned to the groups" Comment: probably done
Allocation concealment (selection bias)	Unclear risk	Comment: probably done
Blinding of participants and personnel (performance bias) All outcomes	High risk	Participants not blinded due to the nature of the intervention
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	Single‐blinded interviewer at FU – blind to allocation BUT cannot use these outcomes
Incomplete outcome data (attrition bias) All outcomes	Low risk	No missing data
Selective reporting (reporting bias)	Unclear risk	No protocol available
Other bias	Low risk	Study appears to be free of other sources of bias
