The Quality Receiver Operating Characteristic Curve Sensitivity, Specificity, and Weighted κ Values

Groups	Random Value of Sensitivity	Random Value of Specificity	Sensitivity	Specificity	κ
1	0.36	0.64	0.61	0.93	0.52
1 and 2	0.50	0.50	0.76	0.82	0.57
1–3	0.56	0.44	0.82	0.75	0.57
1–4	0.67	0.33	0.90	0.61	0.52

The random values of sensitivity and specificity refer to that level of sensitivity and specificity that would be expected by chance. The six groups identified by the Quality Receiver Operating Characteristic Curve are: (1) caudate ≥ 9.8 and posterior vermis < 7.4 and amygdala < 5.7cm³; (2) caudate < 9.8 and posterior vermis < 6.2cm³; (3) caudate ≥ 9.8 and posterior vermis < 7.4 and amygdala ≥ 5.7cm³; (4) caudate < 9.8, posterior vermis ≥ 6.2, and superior temporal gyrus (STG) < 29.4cm³; (5) caudate ≥ 9.8 and posterior vermis ≥ 7.4cm³; and (6) caudate < 9.8, posterior vermis ≥ 6.2, and STG ≥ 29.4cm³.
