Univariate predictors in each numbered model include a visual rating metric plus predictors from the base model.

^*Significant at P < 0.05.

^**Significant at P < 0.01.

^***Significant at P < 0.001.

^{^}0.08 < > 0.05.

CHS = Cardiovascular Health Study. Days Assess–MRI = number of days between assessment and MRI dates. df = degree of freedom. DWMH = deep white matter hyperintensities. FDR = false discovery rate. PC = principal component. PVH = periventricular hyperintensities. WM = white matter.
