Region of interest (ROI) approach (Marsbar): comparison of activation between the skin-picking disorder group and control group within the frontoparietal network, task minus rest contrast

ROI (MNI coordinates)	Contrast value	t statistic	Uncorrected P
Left dorsolateral prefrontal cortex (−22,14, 56)	0.04	0.32	0.375
Right dorsolateral prefrontal cortex (26, 26, 56)	−0.009	−0.67	0.746
Left posterior parietal cortex (−36, −76, 38)	0.04	0.23	0.409
Right posterior parietal cortex (44, −70, 34)	−0.03	−0.16	0.563
Right frontoparietal cortex (28, 50, 2)	0.05	0.36	0.359
