Abbreviations: CI, confidence interval; CIND, cognitive impairment, no dementia; GED, General Educational Development; HR, hazard ratio; IPCW, inverse probability of censoring weights.
a Educational level was dichotomized: high, ≥12 years/high school/GED; low, <12 years/high school/GED.
b P ≤ 0.05 (2-sided).
c Adjusted for baseline age, sex, and marital status.
d Adjusted for baseline age, sex, marital status, and education.
e Adjusted for baseline age, sex, marital status, survey language, and, in overall models, education.
