Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Sequence generation methods were not reported in sufficient detail to perform an adjudication
Allocation concealment (selection bias)	Unclear risk	Method of allocation concealment was not reported in sufficient detail to perform an adjudication
Blinding of participants and personnel (performance bias) All outcomes	High risk	Blinding of participants and/or the investigators was not reported. However, the methods of intervention and control treatment were physically different, and therefore masking of intervention was unlikely
Blinding of outcome assessment (detection bias) All outcomes	High risk	The AIS was a self‐reported measurement. As such, the outcome assessment was conducted by participants who could be aware of the treatment received. We judged the outcome assessment to be at high risk of bias for these outcome measures
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	Not reported in sufficient detail to perform an adjudication
Selective reporting (reporting bias)	Unclear risk	Not reported in sufficient detail to perform an adjudication
Other bias	Unclear risk	It was not clear if there was evidence of imbalance at baseline. Not reported in sufficient detail to perform an adjudication
