Text: Stroke/systemic embolism rates were consistent among older (2. 29 % rivaroxaban versus 2. 85 % warfarin per 100 patient-years ; hazard ratio = 0. 80 ; 95 % confidence interval, 0. 63-1. 02) and younger patients (2. 00 % versus 2. 10 % / 100 patient-years ; hazard ratio = 0. 95 ; 95 % confidence interval, 0. 76-1. 19 ; interaction P = 0. 313), as were major bleeding rates (75 years : 4. 86 % rivaroxaban versus 4. 40 % warfarin per 100 patient-years ; hazard ratio = 1. 11 ; 95 % confidence interval, 0. 92-1. 34 ; < 75 years : 2. 69 % versus 2. 79 % / 100 patient-years ; hazard ratio = 0. 96 ; 95 % confidence interval, 0. 78-1. 19 ; interaction P = 0. 336).
