Table 3.

Differences of ROI-based FC between patients with pED and HCs.

Contrast	Foci	Voxels	BA	MNI coordinate (x, y, z)			t-value
	L dlPFC	581	46	−34	18	40	−4.15
	L AG	552	39	−38	−68	42	−5.55
pED < HCs	L PCC	539	23/29/31	−8	−40	36	−3.82
	L precuneus		31	−2	−64	28	−3.77

Patients with pED manifested lower FC between ROI and left dlPFC, left AG, and left PCC and precuneus than HCs (voxel-level p < 0.001 uncorrected, cluster-level p < 0.05 FWE corrected, cluster size > 20 voxels). pED, psychogenic erectile dysfunction; HCs, healthy controls; L, left; dlPFC, dorsolateral prefrontal cortex; AG, angular gyrus; PCC, posterior cingulate cortex; BA, Brodmann area; MNI, Montreal Neurological Institute.
