Table 4.

Cut-points, ROC values, 95% confidence intervals, sensitivity to patients, and specificity to normals for the following comparisons of patients to normals: normal side, abnormal side, mean of abnormal and normal side (Mean sides), male normal side, male abnormal side, mean of male normal and normal sides (mean male), female normal side, female abnormal side, mean of female normal and abnormal side (mean female).

Group	Best cut-point	ROC value	95% CI	Sensitivity to patients	Specificity to normals
Normal side	1.1	0.67	0.56 – 0.78	0.64	0.56
Abnormal side	1.3	0.69	0.59 – 0.80	0.68	0.60
Mean sides	1.0	0.75	0.65 – 0.84	0.78	0.56
Females, normal side	1.3	0.72	0.598, 0.84	0.71	0.58
Females, abnormal side	1.1	0.68	0.55, 0.81	0.68	0.52
Females, mean sides	1.2	0.76	0.65, 0.87	0.79	0.58
