^*Data reflect unstandardized regression coefficients (b), semipartial η², and p-values illustrating associations of the SES × Race interaction with brain volume measures with adjustment for additional individual covariates, each in separate analyses.

CVD comorbidities variable includes participants with any of the following: coronary artery disease, myocardial infarction, peripheral artery disease, and coronary artery bypass surgery.
