• Following guidelines is no guarantee of a rigorous systematic review • No registered or published protocol • Low methodological (AMSTAR) quality • Low reporting (PRISMA) quality • Funding or sponsor of systematic review not reported • Poor consideration of publication bias |
| Number of systematic reviews included | 238 |
| 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. |
