Abbreviations: BARC, Bleeding Academic Research Consortium; DAPT, dual antiplatelet therapy; HR, hazard ratio; MACCE, major adverse cardiac and cerebral event; MCB, major or clinically relevant nonmajor bleeding; NA, not applicable; NACE, net adverse clinical event; TIA, transient ischemic attack.
Data are expressed as No. of first events of each type (Kaplan-Meier failure %). Hazard ratios (95% CI) are calculated using Cox proportional hazards regression time-to–first event analyses in the intention-to-treat population. Continuity-corrected risk ratios (95% CI) were calculated in case of zero events with a Fisher exact test P value. An interaction P value was tested for a modifying effect of sex (male or female) on the HR scale.
Includes undetermined strokes.
