  1. Model1 adjusted for age, race, smoking status, gender, hypertension, diabetes, and home smokers.
  2. Model2 did not adjust for any covariates.
  3. Tests for linear trend were conducted by modelling categories of BMD as ordinal variables using the median values within each category.
  4. *p < 0.05; **p < 0.01.
