| 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 | Insufficient information to permit judgement |
| Incomplete outcome data (attrition bias) All outcomes | High risk | Completers only |
| Selective reporting (reporting bias) | Unclear risk | Insufficient information to permit judgement |
| Other bias | Low risk | The study appears to be free of other sources of bias |
| Blinding (participant) | High risk | Not possible |
| Blinding (assessor) | Low risk | Assessors blinded |
| 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 | Outcomes immediately post intervention only with no follow‐up |
