Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Computer‐generated by biostatistician
Allocation concealment (selection bias)	Low risk	Sealed envelopes; independent personnel; treatment credibility unequal so used as covariate
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	Attrition fully reported; no test for differences
Selective reporting (reporting bias)	Low risk	Fully reported
Blinding of outcome assessment (detection bias) All outcomes	High risk	Not reported
