Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	‘randomisation was accomplished by using a computer‐generated random numbers table’
Allocation concealment (selection bias)	Unclear risk	Not stated in the manuscript
Blinding (performance bias and detection bias) All outcomes	High risk	Not possible to blind as control group had no intervention
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	146 participants randomized but number completed not reported.
Selective reporting (reporting bias)	Unclear risk	No LBR outcomes reported.
Other bias	Low risk	None known
