Intergroup differences and clinical correlations at the network level.
Compared with the HC group, (A) decreased connectivity strength within the DMN is found in the DMCI group. Compared with the HC and DMCN groups, (B) there are decreased connectivity strength within the CON in the DMCI group. (C) A positive correlation between the connectivity strength within the CON and MMSE scores is found in the DMCI group. (D) A positive correlation between the connectivity strength within the CON and the illness duration is found in the DMCI group.
