Polymer-free sirolimus-eluting stents and polymer-based paclitaxel-eluting stents were associated with comparable risk of death or myocardial infarction ( relative risk = @ ; @ % confidence interval , @-@ @ ; P = @ ) , cardiac death or myocardial infarction ( relative risk = @ ; @ % confidence interval , @-@ @ ; P = @ ) , target lesion revascularization ( relative risk = @ ; @ % confidence interval , @-@ @ ; P = @ ) , and myocardial infarction ( relative risk = @ ; @ % confidence interval , @-@ @ ; P = @ ) .
