Figure 4. Results of mediation models for baseline EF.

Figure 4.

A-C: Results of Preacher and Hayes mediation analyses with significant direct or indirect effects indicated by solid arrows with non-significant direct or indirect effects are shown by dashed arrows. Standardized β-coefficients are shown next to the corresponding path with significant effects shown in bold and non-significant effects in italics. For all models, the total effect of X on Y (c) is shown above the horizontal arrow, while the direct effect of X on Y (c’) after accounting for indirect effects is shown below the horizontal arrow. A: Results indicated that the indirect effects of DMN deactivation and ECN activation did not mediate the significant direct effect of WMH volume on baseline EF. B: Results indicated that the effect of ECN activation on baseline EF was mediated by the total indirect effects of DMN deactivation and WMH volume, but not by either individual indirect effect. C: Results indicated that the effect of DMN deactivation on baseline EF was mediated by the indirect effect of ECN activation but not of WMH volume.
