Notes	—
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	RCT: random permuted blocks of variable length
Allocation concealment (selection bias)	Low risk	Sealed, serially numbered envelopes
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	Not stated
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	Not stated
Incomplete outcome data (attrition bias) All outcomes	Low risk	The trial included all randomized participants in the analysis
Selective reporting (reporting bias)	Low risk	The trial reported over 90% of the included participants in the final analysis
Other bias	Unclear risk	We did not detect any other sources of bias
