Note: SE = standard error; MCI = mild cognitive impairment.
aFemale was treated as the reference category for sex.
bThe number of comorbid conditions was calculated excluding MCI.
cDue to multicollinearity, age, years of education, time since MCI diagnosis, and the number of comorbid conditions were mean centered for main and interaction effects.
