SES = socioeconomic status; BMI = body mass index; CRP = C-reactive protein; CES-D = Center for Epidemiologic Studies-Depression scale; WMLV = white matter lesion volume; R = right; L = left. Demonstration of the main effects of SES with regional fractional anisotropy in the additional models that include a sensitivity variable. ^∗p < 0.05, ^∗∗p < 0.01, ^∗∗∗p < 0.001. Data reflect standardized regression coefficients (β) and semipartial correlations squared (sr²). ^aBase model includes SES, race, age, and sex.
