Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Envelope method
Allocation concealment (selection bias)	Unclear risk	Not stated
Blinding (performance bias and detection bias) All outcomes	Low risk	Open‐label Blinding of treatment: no Blinding of assessor: not stated Blinding of data analysis: not stated
Incomplete outcome data (attrition bias) All outcomes	Low risk	Primary analysis was by intention‐to‐treat.
