Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Comment: The method of sequence generation was not reported.
Allocation concealment (selection bias)	Unclear risk	Comment: There is no mention of any measures taken to conceal allocation
Incomplete outcome data (attrition bias) All outcomes	Low risk	Quote: "all the participants who were randomised were included in the outcome analysis." Comment: 2 participants dropped out of the treatment group. Reasons for drop‐out are not fully reported.
Selective reporting (reporting bias)	Low risk	Comment: All specified outcomes were reported.
Other bias	High risk	Comment: The authors acknowledged having little information about the interventions prescribed as part of TAU. The issue of researcher allegiance cannot be ruled out. Treatment adherence was not monitored.

Blinding of outcome assessment (detection bias) All outcomes	Low risk	Quote: "we aimed at keeping interviewers blind to each participants condition."
