| Aim | To assess systematic review definitions that are published in overviews of systematic reviews, published in the medical literature between November 2017 and May 2018. |
| Level of Investigation | Descriptive |
| Summary of Findings | Only 8% of overviews explicitly reported a systematic review definition, whereas 24% of overviews reported heterogeneous information about the criteria that were used to include systematic reviews in the overviews. 68% of overviews did not report any definition/criteria for including a systematic review. 2% of overviews reported a definition based on reproducibility, and none of the overviews reported the need to search for grey and unpublished literature for a review to be considered systematic. |
| Number of systematic reviews included | 105 |
| Number of eligible systematic reviews assessed | 138 |
