Figure 3 Comparative Unadjusted Rates of MACE for Overall Population and Subgroups

Hazard ratios (HRs) of stent type for MACE in the overall patient population and specified subgroups. *These 3 subgroups show statistically significant unadjusted HRs. However, the male and prior coronary artery bypass graft (CABG) subgroups become nonsignificant when adjusted by propensity score. Saphenous vein graph (SVG) lesions remain significant (HR 2.38; 95% CI 1.21 to 4.69; p = 0.012). LAD = left anterior descending artery; STEMI = ST-segment elevation myocardial infarction; other abbreviations as in Figures 1 and 2.
