Figure 4From: Identifying diabetic patients with cardiac autonomic neuropathy by heart rate complexity analysisROC curves. ROC (receiver operating characteristics) curves showing true positive (sensitivity) and false positive rate (1-specificity) for various thresholds using sample entropy (SampEn) (Panel A) and SD1/SD2 (Panel B) across 9 CAN+ subjects and 8 CAN- subjects. Areas under ROC curves are 0.79 and 0.70 for SampEn and SD1/SD2 respectively.Back to article page
