Comparative Effectiveness of Rivaroxaban and Warfarin for Stroke Prevention in Multi-morbid Patients With Nonvalvular Atrial Fibrillation

The overall goal of this study is to evaluate the comparative safety and effectiveness of
rivaroxaban vs. vitamin K antagonist (VKA) for stroke prevention in patients with nonvalvular
atrial fibrillation (NVAF) across risk profiles and comorbidities that reflect everyday
clinical practice.

The primary objective in this study is to evaluate the combined end point of stroke or
systemic embolism (SSE), and major bleeding in NVAF patients treated with rivaroxaban vs.
VKA.
