CI, confidence interval; CHD, coronary heart disease.
Model 1 was adjusted for age.
Model 2 was adjusted for variables in model 1 plus body mass index, total cholesterol, hypertension, diabetes, smoking status, and alcohol drinking status.
Model 3 was adjusted for variables in model 2 plus high-density lipoprotein cholesterol.
The model for total participants (in which the sexes were combined) was also adjusted for sex.
Crude mortality rate is shown as per 1,000 person-years.
