Correlation between FC strength and electrophysiological index in patients with DCM.

Electrophysiological index	Seeds/Sources	Region	Cluster size	P value	T value	x	y	z
R CMCT	L primary motor cortex (BA 4)			n.s
L CMCT	R primary motor cortex (BA 4)	Precneous	830	0.0016	4.94	4	− 66	22
R SEP amplitude	L primary somatosensory cortex (BA 1, 2, 3)			n.s
	L thalamaus	L precentral gyrus	249	0.0037	5.74	− 34	0	40
	L lateral part of sensorimotor network			n.s
L SEP amplitude	R primary somatosensory cortex (BA 1, 2, 3)			n.s
	R thalamaus			n.s
	R lateral part of sensorimotor network	R lateral occipital cortex	301	0.0006	− 5.2	44	− 70	− 16
		Cingulate gyrus anterior division	149	0.0056	5.34	4	4	42

x, y, and z represent the local maximum in a cluster in the MNI coordinate. T value is the t value of a local maximum.

Cluster-level threshold was p < 0.05 (false discovery rate corrected). Bonferroni correction was further applied to the cluster-level threshold (p < 0.00625).
