| Aim | To identify the potential impact of searching a limited number of databases in systematic reviews (SRs) using two reviews published in 2023 on the same topic as examples. |
| Level of Investigation | Descriptive |
| Summary of Findings | From two systematic reviews published in 2023 on the same topic. The two reviews of overlapping topics published in 2023, included 16 and 11 studies. Among these, only 4 studies were included in both reviews, suggesting that both reviews missed multiple eligible studies. Both reviews only searched 2 databases and neither reported grey literature searching. One review retrieved 11,695 citations and included 7 studies, the other 1,058 citations and included 12 studies. An assessment using AMSTAR 2 showed that neither of the reviews explained their selection of the study designs for inclusion, used a comprehensive literature search strategy, or provided a satisfactory explanation for any heterogeneity observed in the results. |
