Figure 1: Receiver-operating characteristic curves showed the performance of resting heart rate (HR), diabetes (DM), and categorical variable of DM-HR in predicting cardiovascular autonomic neuropathy (CAN) prevalence in this dataset. The 95% confidence interval (CI) is given in parentheses. AUC represents area under the curve. HR: AUC = 0.719, 95% CI 0.690–0.748, ; DM: AUC = 0.589, 95% CI 0.556–0.622, ; DM-HR: AUC = 0.738, 95% CI 0.710–0.766, .
