Figure 1 Overall Survival and Survival Free of Q-Wave MI by Randomized Treatment
The blue solid lines indicate coronary artery bypass grafting (CABG), and percutaneous transluminal coronary balloon angioplasty (PTCA) by red dashed lines. MI = myocardial infarction.
Figure 3 10-Year Survival Rates for Patients According to Subgroups Based on Characteristics at Study Entry
Ninety-nine percent confidence intervals of the absolute treatment difference between 10-year survival rates are shown for each subgroup. The test of the interaction between treatment effect and subgroup is based on proportional hazards models. CABG = coronary artery bypass grafting; CCS = Canadian Cardiovascular Society classification of angina; CHF = congestive heart failure; ECG = electrocardiogram; LAD = left anterior descending coronary artery; LV = left ventricular; MI = myocardial infarction; PTCA = percutaneous transluminal coronary balloon angioplasty; PVD = peripheral vascular disease.
Figure 4 Overall Survival by Randomized Treatment Stratified by Diabetes Status
Patients who were being treated for diabetes at baseline are shown with heavy lines, and all other patients are shown with light lines. The blue solid lines indicate CABG, and the red dashed lines indicate PTCA. D = treated diabetes; ND = no treated diabetes; other abbreviations as in Figure 1.
