Table 3

Receiver operating characteristic curve analysis for the cross-sectional area at different levels of the median nerve in diabetic peripheral neuropathy patients.

MN level	AUC	Sensitivity	Specificity	Optimal threshold for CSA
MN1	0.69	0.53	0.80	12.05
MN2	0.72	0.50	0.82	11.79
MN3	0.70	0.67	0.67	7.85
MN4	0.67	0.77	0.57	7.62
MN5	0.75	0.90	0.57	9.86
MN6	0.87	0.93	0.70	10.71
MN7	0.88	0.73	0.88	12.42

AUC, area under the receiver operating characteristic curve; CSA: cross-sectional area (mm²); MN: median nerve; : thickness (mm); : width (mm).
