Text: Polymer-free sirolimus-eluting stents and polymer-based paclitaxel-eluting stents were associated with comparable risk of death or myocardial infarction (relative risk = 1. 17 ; 95 % confidence interval, 0. 49-2. 80 ; P =. 71), cardiac death or myocardial infarction (relative risk = 1. 17 ; 95 % confidence interval, 0. 72-1. 89 ; P =. 50), target lesion revascularization (relative risk = 0. 98 ; 95 % confidence interval, 0. 65-1. 47 ; P =. 93), and myocardial infarction (relative risk = 1. 79 ; 95 % confidence interval, 0. 85-3. 76 ; P =. 12).
