In the article by Amin et al., “Comparative clinical outcomes between direct oral anticoagulants and warfarin among elderly patients with non-valvular atrial fibrillation in the CMS Medicare population” which was published online on March 28, 2019 (J Thromb and Thrombolysis 48:240–249), 2019, corrections are needed.
Due to an error in the underlying data cut received by the authors for the CMS Medicare database, a proportion of Medicare patients who should have been included in the analysis were inadvertently excluded. Specifically, those excluded patients were newly diagnosed with atrial fibrillation and initiated anticoagulation therapy in the same calendar year (2014 or 2015).
The authors have corrected the analyses by adding back those inadvertently excluded patients. Results sections in the abstract and main body of the article, Figs. 1, 2, 3, Tables 1, 2, and Supplemental Table 1 have been changed to reflect the corrected analyses. These corrections have increased the sample size from 198,321 to 366,425 patients.
Overall, the updated results were consistent with the original analyses. One change in statistical significance was observed for dabigatran versus warfarin: while directionally consistent with the original analysis, this updated analysis showed a lower risk of stroke/SE for dabigatran compared with warfarin. No other changes were observed in conclusions for either the direction of or the statistical significance for the comparative results.
