| Aim | To assess the frequency of reviewers who authored included studies (dual co-authorship) of overview systematic reviews with the included systematic reviews and the impact on quality rating, if any. Both Cochrane and non Cochrane systematic reviews were included. |
| Level of Investigation | Descriptive |
| Summary of Findings | From the included sample of 98 systematic reviews, 51% of non-Cochrane reviews and 90% of Cochrane overviews had included at least one systematic review with dual co-authorship (reviewers who authored included studies). Higher quality scores were given to reviews in systematic overviews where dual co-authorship was present for both Cochrane and non-Cochrane reviews. |
