Fig. 2.

Age associations with white matter are more pronounced following higher ELS severity.

Note. A) Simple slopes of age on white matter fiber density and cross-section (FDC) at different levels of ELS severity. ELS is grouped as -1 SD, average, and +1 SD values only for visualization purposes. These simple slopes are described in Table 3. B) Johnson-Neyman plots showing continuous values of ELS severity where the slope of age on FDC was significant vs. not, and the magnitude of slopes. FDC = fiber density and cross-section; ILF = inferior longitudinal fasciculi; IFOF = inferior fronto-occipital fasciculi; Forcmin = forceps minor; UF = uncinate fasciculi; ATR = anterior thalamic radiations; SLF = superior longitudinal fasciculi. Only tracts that exhibited significant age by ELS interactions following FDR correction are displayed.
