Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	"...assigned randomly."
Allocation concealment (selection bias)	Unclear risk	Insufficient information to permit judgment.
Blinding (performance bias and detection bias) Patients and providers	High risk	No blinding.
Blinding (performance bias and detection bias) Assessors	Unclear risk	It is not stated whether the assessors were blinded.
Incomplete outcome data (attrition bias) All outcomes	High risk	28% attrition at 1 month, 31% attrition at 6 months, and 38% attrition at the 12 months follow‐up. Balanced across groups. Not clear whether ITT was performed. Reasons for loss not reported.
Selective reporting (reporting bias)	Low risk	The published report included all expected outcomes based on the study hypotheses.
Other bias	Low risk	Collateral report to check on self‐report. There were no differences between groups at baseline. No additional sources of bias appear to be present.
