In the fully adjusted model including Total WMH and CMC, standardized β coefficients were −0.005 (95% CI, −0.064 to 0.054; p = 0.87) for reaction time, −0.007 (95% CI, −0.065 to 0.052; p = 0.82) for Trail Making Test–B, −0.058 (95% CI, −0.116 to −0.001; p = 0.046, nominally significant) for fluid intelligence, and −0.019 (95% CI, −0.110 to 0.072; p = 0.68) for digit span.
