All comparisons of continuous variables used pooled, two-tailed t-tests with 208 df, except for analyses of subjective social support which used a Satterthwaite t-test with 198 df due to unequal variances. Age and education variables presented in years, white matter hyperintense lesion (WML) volume presented in milliliters.
