Subgroup analyses for mortality after treatment with coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI). LAD, left anterior descending artery; LV, left ventricular; MI, myocardial infarction; PVD, peripheral vascular disease. The vertical line indicates a hazard ratio of 1.0, equivalent to no difference between treatment groups. a Based on the full duration of follow-up in all trials. b Pooled unadjusted 5-year Kaplan-Meier survival rates. cP value for the treatment by covariate interaction. d The analysis that compares patients enrolled in balloon angioplasty trials and bare-metal stent trials is pooled and not stratified by study.
