| Aim | To assess consistency of risk of bias judgements for trials included in multiple reviews from the Cochrane Gynaecology and Fertility group in the field of subfertility. |
| Level of Investigation | Descriptive |
| Summary of Findings | From 34 Cochrane reviews including 46 duplicated trials, there were 156 bias judgments that were completed by at least two separate groups of authors and appeared in systematic reviews in the Cochrane Library. In 45% of cases, these risk of bias judgments differed. For random sequence generation there was 29% disagreement; For allocation concealment there was 41% disagreement; for blinding there was 65% disagreement; for incomplete outcome reporting there was 30% disagreement; and for selective reporting there was 57% disagreement. |
