In all cases, 110 subjects (48 females and 62 males) were considered. aNull hypothesis: area = 0.5. bPositive if assessment is more than or equal to the optimal cut-off point; it was calculated as the minimum value of the square root of the following: [(1 − sensitivity)2 + (1 − specificity)2], and greater accuracy is reflected by a smaller distance to point (0, 1) in the ROC curve. cPPV: predictive positive value. dPNV: predictive negative value. eSignificant values. |
