Figure 5From: Identifying diabetic patients with cardiac autonomic neuropathy by heart rate complexity analysisTree classifications. Classification tree illustrating the combination of threshold values of SampEn and SD1/SD2, characterizing CAN+/- in the study. Tree (A) shows accuracy = 82.35%, sensitivity = 100% and specificity = 62.5%. Tree (B) shows accuracy = 88.24%, sensitivity = 100% and specificity = 75.0%. All individual numerical values are indicative of the number of subjects in each terminal node of the tree. TP: true positive, FP: false positive, TN: true negative; FN: false negative.Back to article page
