Significant values are in [bold].
Note: BMD values are presented as raw variables without any transformation.
Model 1a: no covariates were adjusted; Model 2b: adjusted for sex, age, and race; Model 3c: adjusted for age, race, sex, education, ratio of family income to poverty, marital status, body mass index, alcohol intake, smoking status, diabetes, and hypertension.
