Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Quote: “were randomly divided into.” Comment: Randomisation was stated but no information on method used was available; therefore risk of selection bias was considered to be unclear.
Allocation concealment (selection bias)	Unclear risk	No quotes available. Insufficient information to permit judgement. Comment: Owing to insufficient information, allocation concealment was considered to have unclear risk of bias.
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	No quotes available. No blinding described. Comment: Owing to insufficient information, risk of performance bias was considered to be unclear.
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	No quotes available. No blinding of outcome assessments described. Comment: Owing to insufficient information, risk of detection bias was considered to be unclear.
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	No quotes available. Comment: Owing to insufficient information to permit judgement, risk of attrition bias was considered to be unclear.
Selective reporting (reporting bias)	Low risk	No quotes available. Expected outcomes were reported according to objectives. Comment: Risk of reporting bias was therefore considered to be low.
Other bias	Unclear risk	No quotes available. Baseline data are missing. Comment: Owing to lack of information at baseline, risk of other bias was considered to be unclear.
