Similarly , the pooled bioactive stent group was associated with a risk ratio of 0.71 for cardiac death ( 95 % confidence interval , 0.26-1 .95 ; P = .51 ) , 0.44 for recurrent myocardial infarction ( 95 % confidence interval , 0.20-0 .97 ; P = .04 ) , and 1.39 for ischemia-driven target lesion revascularization ( 95 % confidence interval , 0.74-2 .59 ; P = .30 ) , compared to the pooled drug-eluting stent group .
