Kaplan-Meier Curves for the Primary End Point, According to the Intention-to-Treat Analysis. The primary end point was the first centrally adjudicated occurrence of death from any cause, nonfatal reinfarction, or NYHA class IV heart failure requiring hospitalization or a stay in a short-stay unit. Kaplan-Meier estimates of the cumulative event rates in the PCI group and the medical therapy group, respectively, were 14.8% and 13.1% at 3 years, 17.2% and 15.6% at 4 years, and 21.2% and 16.4% at 5 years. The cumulative yearly adjusted hazard ratios for PCI versus medical therapy for years 1 through 5 were 1.13, 1.18, 1.14, 1.13, and 1.16, respectively. The P value was calculated with the use of the log-rank test. (Hochman et al. NEJM Dec 7, 2006 p2403)
