Education was grouped into three categories: low (elementary school), medium (secondary school), and high (university).
aLow: none or primary school; medium: middle school; high: high school, trade school or university.

We created three levels of education: low (finished less than elementary school), medium (elementary school), high (general intermediate, and lower vocational education, university, college, higher vocational, general secondary, and intermediate vocational education).
Baseline covariates were age (40 49, 50 59, and 60 69 years), ethnicity (white, black/African American, and other), and education (low, lower than high school; medium, high school or some college; and high, college and higher).
Education was defined at three levels, where low education was completion of ≤9 years in school, medium education was between 10 and 12 years in school, and high education was ≥13 years in school, i.e. university/academic graduation.
