| Summary of Findings | From 144 included systematic reviews evaluating direct oral anticoagulants in patients treated for an acute venous thromboembolism indexed in PubMed from inception to January 31, 2022. 26 systematic reviews (18.1%) were classified as original, 87 (60.4%) as conceptual replications, and 31 (21.5%) as excessive replications (redundant). The risk of bias was high in 19 (73.1%) of the original systematic reviews, 65 (74.7%) of the conceptual replications, and 21 (67.7%) of the excessive replications. Compared to the original systematic reviews, the overall methodological quality was not improved in either conceptual or excessive replications. |
