Notes: aAssumed equal to stroke and systemic embolism. bTotal number of events among 16,741 Finnish AF patients using warfarin were 375 for stroke and 99 for ICH.31 Assuming a full follow-up of one year for each patient, these were converted to a rate per 100 patient-years: 2.27 and 0.59, respectively. cTotal number of bleeding events in 125,261 Finnish patients using warfarin was 5412,32 and the corresponding rate was 4.32 per 100 patient-years. By subtracting the ICH rate from total bleeds, the rate for other major bleeds was estimated at 3.73 per 100 patient-years. dSecondary analysis of ARISTOTLE-trial. e1.900 per 100 patient-years for warfarin.33 f0.1 per 100 patient-years for warfarin.8 gSecondary analysis of AVERROES-trial, all treatments assumed equal.
