Figure 1 Kaplan-Meier estimates of the overall survival and repeat revascularization rate of type 2 diabetic patients following coronary artery bypass graft surgery (CABG), according to the presence or absence of diabetic retinopathy (DR). (A) The overall survival curves; (B) subsequent revascularization curves. DR = diabetic retinopathy. The p values were calculated by the log-rank test. I bars indicate 95% confidence intervals.

Figure 2 Kaplan-Meier estimates of the overall survival of type 2 diabetic patients following coronary artery bypass graft surgery (CABG), according to presence or absence of renal dysfunction (RD) (serum creatinine  1.4 mg/dl). DR = diabetic retinopathy. The p values were calculated by the log-rank test. I bars indicate 95% confidence intervals.

Figure 3 Kaplan-Meier estimates of the overall survival of type 2 diabetic patients following coronary artery bypass graft surgery (CABG), according to the presence or absence of left-ventricular dysfunction (VD) (ejection fraction <50%). DR = diabetic retinopathy. The p values were calculated by the log-rank test. I bars indicate 95% confidence intervals.

Figure 4 Kaplan-Meier estimates of the overall survival of type 2 diabetic patients following coronary artery bypass graft surgery (CABG), according to the presence or absence of internal thoracic artery (ITA) grafting. DR = diabetic retinopathy. The p values were calculated by the log-rank test. I bars indicate 95% confidence intervals.

Figure 5 Kaplan-Meier estimates of the overall survival of type 2 diabetic patients following coronary artery bypass graft surgery (CABG), according to severity of diabetic retinopathy (DR). Overall survival curves were stratified separately according to severity of diabetic retinopathy. The p values were calculated by the log-rank test. I bars indicate 95% confidence intervals. NPDR = nonproliferative diabetic retinopathy; PDR = proliferative diabetic retinopathy.
