Regions	Optimal cut-off	AUC(95%CI)	Sensitivity	Specificity	Accuracy	Negative predicate value	Positive predicate value
Right superior frontal gyrus (12, 42, 48)	103.86	0.803 (0.668–0.939)	92.3% (75.9%–98.6%)	61.1% (38.6%–79.7%)	79.5%	84.6%	77.4%
Right superior frontal gyrus (18, −6, 70)	99.51	0.829 (0.696–0.963)	84.6% (66.5%–93.9%)	83.3% (60.8%–94.2%)	84.1%	78.9%	88.0%
Right superior parietal lobule (34, −56, 58)	99.01	0.825 (0.693−0.957)	65.4% (46.2%−80.6%)	88.9% (67.2%−98.0%)	75.0%	64.0%	89.5%
