Fixed Minidose Warfarin and Aspirin Alone and in Combination vs Adjusted-Dose Warfarin for Stroke Prevention in Atrial Fibrillation

Although the difference was insignificant, adjusted-dose warfarin seemed superior to minidose warfarin and to warfarin plus aspirin after 1 year of treatment. The results do not justify a change in the current recommendation of adjusted-dose warfarin (INR, 2.0-3.0) for stroke prevention in atrial fibrillation.
