GM volume regions positively correlated with the scores on the FCSRT independently for groups A₁ and B₁ using VBM

Group (score)	P	Brain region	Side	BA	k	x	y	z	T
A1 (TR), n = 50	0.001	Parahippocampal g.	L	35/36	50/283	–28	–15	–28	3.62
		Hippocampus		NA	16/283	–34	–16	–21	3.47

A1 (FR), n = 50	0.001	Mid. Frontal g.	L	NA	16	–31	–1	49	3.41
B1 (TR), n = 18	0.001	Insula	R	13	88/170	42	3	0	4.38
B1 (FR), n = 18	0.001	Precentral g.	R	4	62/63	28	–30	60	5.60

Statistical analyses were performed including age, gender, education level, total GM volume and centre as nuisance covariates, with a threshold of P = 0.001, uncorrected, including a minimal k of 50 voxels except for the FR in group A₁
