| Level of Investigation | Analytical |
| Summary of Findings | From 238 included systematic reviews of type 2 diabetes mellitus indexed on PubMed between 2005 and 2018, higher scores were noted for registered reviews, relative to non-registered reviews (AMSTAR-2 mean score: 18.0 vs. 14.5, P = 0.000; PRISMA mean score: 20.4 vs. 17.6, P = 0.000). AMSTAR-2 and PRISMA scores were associated with registration status, country of the first author, and statistical results. The proportion discussing publication bias and reporting funding sources were <40% for both registered and non-registered systematic reviews. |
