Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Blocked randomisation using random table computer‐generated numbers
Allocation concealment (selection bias)	Low risk	Sealed opaque envelopes
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	Not feasible due to nature of intervention
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	Not mentioned
Incomplete outcome data (attrition bias) All outcomes	Low risk	ITT not mentioned, but is probably the case looking at Figure 1. no missing data or cases.
Selective reporting (reporting bias)	Low risk	All pre‐specified outcome measures were reported,
Other bias	Low risk	No other bias detected
