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.
