Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Quote: participants were prospectively randomised. Comment: methods for the generation of sequence not described
Allocation concealment (selection bias)	Unclear risk	Quote: participants were prospectively randomised. Comment: methods used for allocation sequence generation not described
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	Insufficient information to permit judgement
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	Report gives the impression that there were no dropouts or withdrawals, but this was not specifically stated
Selective reporting (reporting bias)	Unclear risk	Protocol not obtained; all outcomes stated in methods reported
