This document appears to be discussing a study comparing the efficacy and safety of direct oral anticoagulants (DOACs) vs warfarin in treating patients with atrial fibrillation. The study found that DOACs were as effective as warfarin in reducing stroke and systemic embolism risks while causing fewer bleeding issues. DOACs may be a safer alternative for patients with atrial fibrillation compared to long-term warfarin treatment.
