Kaplan-Meier cardiac event–free survival curves: coronary artery bypass grafting (CABG) versus percutaneous revascularization (PCI) (A), Kaplan-Meier target vessel revascularization (TAVER)–free survival curves: CABG versus PCI (B), Kaplan-Meier survival curves: CABG versus PCI (C).

Logarithms (Ln) of the 95% confidence interval (CI) for adjusted hazard ratio of percutaneous revascularization (PCI) patient death and cardiac event to coronary artery bypass grafting (CABG) patient death and cardiac event (A), PCI patient death and target vessel revascularization (TAVER) to CABG patient death and TAVER (B), and PCI patient death to CABG patient death (C). A logarithm of the 95% CI whose lower limit is above 0 (the 95% CI is above 1) indicates that the adjusted hazard ratio of PCI is significantly higher than CABG, namely CABG has significantly better freedom from the risk. On the other hand a logarithm of the 95% CI whose upper limit is below 0 (the 95% CI is below 1) denotes that adjusted hazard ratio of PCI is significantly lower than CABG, namely PCI has significantly better freedom from the risk. (All= the entire patient cohort;LAD[+]= patients with significant proximal left anterior descending artery lesion;LAD[−]= patients without significant proximal left anterior descending artery lesion;Young= patients younger than 65 years;Elderly= patients older than 64 years.)
