Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Computer generated random number sequence
Allocation concealment (selection bias)	Low risk	Generated list was used by an independent person for group allocation
ITT analysis	Low risk	Results were analysed on an ITT basis
Blinding of outcome assessment (detection bias) primary outcome	Low risk	Assessors were blinded to group allocation
