Relative risk plots comparing TE, MB, and deaths during the Fiix and PT periods. (A) Outcomes in all maintenance-phase warfarin patients. Data are based on event counts during the PT and Fiix periods in patients treated beyond the first 60 days on warfarin and show the number of events, event incidence (% ppy), RR, and P value. (B) Outcomes in long-term warfarin patients only (ie, patients treated with warfarin for >360 days prior to entering the study group).
