Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Not reported
Allocation concealment (selection bias)	Unclear risk	Not reported
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	Not reported
Incomplete outcome data (attrition bias) All outcomes	High risk	High attrition: intervention (40%), control (33%) Adherence to intervention not reported
Selective reporting (reporting bias)	High risk	No protocol identified. The study authors reported no statistically significant differences between intervention and control groups, which meant that it was not possible to include this study in meta‐analyses. This has the potential to lead to an overestimate of effectiveness for those outcomes.
Other bias	Low risk	Appeared free from other sources of bias.
