Primary outcomePrimary: The Composite Event of Stroke/Non-CNS Systemic Embolism: Primary Efficacy (Non-Inferiority) — 188; 241 Patients — p=<0.001
Summary
The purpose of this study is to compare the efficacy and safety of rivaroxaban with warfarin for the prevention of blood clots in the brain (referred to as stroke) and blood clots in other parts of the body referred to as non-central nervous system systemic embolism) in patients with non-valvular atrial fibrillation (a heart rhythm disorder).
