Fig. 4From: Recurrent and concurrent patterns of regional BOLD dynamics and functional connectivity dynamics in cognitive declineGroup difference of dfALFF and dFC states between HC, SCD and MCI. a The occurrence frequency of dFC state 3 is significantly different among the three groups. SCD showed significantly reduced occurrence frequency compared with HC (p = 0.01), and MCI showed significantly reduced occurrence frequency compared with HC (p = 0.0003). b The co-occurrence frequency of dfALFF state 2 and dFC state 3 is significantly different among the three groups. MCI showed significantly reduced co-occurrence frequency compared with SCD (p = 0.01), and MCI showed significantly reduced co-occurrence frequency compared with HC (p = 0.008)Back to article page
