Abstract
Numerous real-world studies estimating major bleeding rates in rivaroxaban patients with nonvalvular atrial fibrillation have been published. We performed a meta-analysis to better quantify the rates of different types of major bleeding seen with rivaroxaban in observational studies. The pooled rates of major bleeding with rivaroxaban were generally low and consistent with those reported in its pivotal randomized controlled trial.
