Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Random number table
Allocation concealment (selection bias) Low risk Unblinded
Blinding (performance bias and detection bias) 
 All outcomes Unclear risk No evidence the analyst was blinded
Incomplete outcome data (attrition bias) 
 All outcomes Unclear risk Unclear if there were losses to follow‐up
Selective reporting (reporting bias) Low risk No problems identified
Other bias Low risk No problems identified
