Table 4 Regional node analyses of the functional brain network revealed by NBS

Node			Weighted node degree				p value	r
L/R	BA	Brain region	Multi-domain		Visuomotor
L/R	BA	Brain region	M (SD)	Mdn	M (SD)	Mdn
L	17b	Lingual gyrus, occipital	32.00 (5.74)	31.69	26.74 (5.54)	27.22	.022	0.42
L	17a	Lingual gyrus, occipital	29.06 (10.36)	27.61	21.11 (8.66)	20.20	.032	0.40
R	7	Precuneus	17.39 (8.03)	17.77	11.66 (4.13)	10.36	.015	0.45
R	5	Paracentral lobule	16.21 (8.66)	16.73	9.29 (4.00)	8.37	.015	0.45

Nodes of the network in the theta band that differ in weighted node degree between the multi-domain group and the visuomotor group are displayed
L, left hemisphere; R, right hemisphere; BA, Brodmann area derived from sLORETA; M, mean; SD, standard deviation; r, effect size. The weighted node degree was compared between groups with the Mann–Whitney U test. Exact p values are reported uncorrected
