Notes  
Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Unclear risk Insufficient information to permit judgement
Allocation concealment (selection bias) Unclear risk Not described
Incomplete outcome data (attrition bias) 
 All outcomes High risk No intention‐to‐treat analysis
Selective reporting (reporting bias) Low risk Although data difficult to access
Other bias Low risk The study appears to be free of other sources of bias
Blinding (participant) High risk Not possible
Blinding (assessor) Unclear risk Not stated
Were the treatment and control group comparable at entry? Unclear risk Insufficient information to permit judgement
Was the surveillance active, and of clinically appropriate duration (i.e. at least 3 months post intervention)? High risk No follow‐up after the intervention year of the study
