The adjusted hazard ratios for mortality were 2.52 (95% confidence interval [CI]: 1.92\u20133.30) for nonsmokers, 0.52 (95% CI: 0.32\u20130.84) for pre\u2010PCI quitters, and 0.11 (95% CI: 0.06\u20130.22) for post\u2010PCI quitters, compared to persistent smokers. With respect to additional revascularizations, a higher risk was observed among the quitters (1.70 [95% CI: 1.40\u20132.08] for pre\u2010PCI quitters and 1.59 [95% CI: 1.36\u20131.85] for post\u2010PCI quitters) as well as the nonsmokers (1.40 [95% CI: 1.20\u20131.64]).
