| Aim | To assess how cross-over studies included in a Cochrane Systematic Reviews are quality appraised in order to assess their risk of bias. |
| Level of Investigation | Descriptive |
| Summary of Findings | None of the included reviews undertook a risk of bias assessment specific for the included cross-over studies. Items specific for cross-over studies were seldom considered anywhere in quality assessment of the reviews. When the authors reassessed the risk of bias, including 3 items specific to cross-over trials, a low risk of bias was judged for appropriate cross-over design in 79%, carry-over effects in 34% and for reporting data in all stages of the trial in 82%. |
