Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Block randomisation (groups of 4 with 2 in each treatment arm and thus allowed a
 maximum difference of two patients per group per stratum)
Allocation concealment (selection bias) Low risk Performed with the use of sealed envelopes
Blinding of participants and personnel (performance bias) 
 All outcomes High risk Open‐label
Blinding of outcome assessment (detection bias) 
 All outcomes Low risk All endpoints specified in the protocol were adjudicated by an independent committee whose members were unaware of the patients’ treatment assignments
Incomplete outcome data (attrition bias) 
 All outcomes Unclear risk 3/160 lost to follow‐up (2%)
Selective reporting (reporting bias) Low risk Important patient‐level outcomes provided
Other bias High risk Data not independent of sponsor
