Regions showing aFCS/rFCS differences between iSCD and healthy controls

FCS	Brain regions	BA	Cluster size	Peak MNI coordinates, mm			T value
				x	y	z
	Right calcarine	17/19	1130	21	−63	6	4.68
	Right cuneus	18/19		3	−81	24	4.61
	Left calcarine	17/19		−12	−72	9	4.53
aFCS	Left parietal	7/40	792	−42	−57	54	4.42
	Left precuneus	5/7		−12	−54	57	4.22
	Medial superior frontal	10/11	319	0	60	27	3.94
rFCS	Left precuneus/posterior cingulate cortex	7/31	188	0	−69	39	4.96

Abbreviations: FCS, functional connectivity strength; BA, Brodmann's area; MNI, Montreal Neurological Institute; T value, T-statistic value; aFCS, absolute functional connectivity strength; rFCS, relative functional connectivity strength; iSCD, informant-reported subjective cognitive decline.
