Fig 3.
Receiver operating characteristic (ROC) curve of number of VPT frequencies over normal predicting diabetic foot ulcers.
Number of low frequencies (4 or 8 Hz) over normal range: AUC = 0.91[0.84-.096], p = 3.1x10-14. Number of median frequencies (16 or 32 Hz) over normal range: AUC = 0.84[0.77–0.92],p = 1.3x10-10. Number of high frequencies (64 or 125 Hz) over normal range: AUC = 0.83[0.76–0.91], p = 4.0x10-10. Number of all frequencies over normal range: AUC = 0.89[0.83–0.94], p = p = 5.3x10-13.
