Table 4. One sample t-test of function connectivity between each two patient groups.

Connecting Masks	t-test p(AD-MCI)	t-test p(AD-NC)	t-test p(MCI-NC)
PRC_R ~ Tail_R	0.484	0.008*	0.036*
PRC_L ~ Tail_R	0.022*	0.010*	0.022*
PHC_R ~ Head_R	0.003*	0.03*	0.193

Note: The symbol “~“denotes function connectivity between each pair. The symbol “^*“ indicates p values <0.05.
