Fig. 5: Moderated mediation model of Ecog memory score.

A PSQI moderated the mediating effect of rich-club SC-FC coupling on the association between DTI-ALPS and Ecog Memory. B Rich-club SC-FC coupling negatively mediated association between DTI-ALPS and Ecog Memory in good sleepers. C Rich-club SC-FC coupling failed to mediate the association between DTI-ALPS and Ecog Memory in poor sleepers. CI is 95% bootstrapping confidence interval of conditional indirect effect.
