By 30 days, the primary composite end point had occurred among 9.2% of patients in the bivalirudin group vs 10.0% of patients in the heparin-plus-Gp IIb\/IIIa group (odds ratio, 0.92; 95% confidence interval, 0.77-1.09;\n P<\/jats:italic>\n = .32). The secondary composite end point occurred in 7.6% of patients in the bivalirudin vs 7.1% of patients in the heparin-plus-Gp IIb\/IIIa groups (odds ratio, 1.09; 95% confidence interval 0.90-1.32;\n P<\/jats:italic>\n = .40). Prespecified statistical criteria for noninferiority to heparin plus Gp IIb\/IIIa were satisfied for both end points.
