Model 1 was unadjusted

Model 2 was adjusted for sex, age, race, education, marital status, and poverty income ratio

Model 3 was further adjusted for BMI, smoking status, drinking status, physical activity, hypertension, hyperlipidemia, antihyperglycemic treatment, lipid-lowering treatment, and antihypertensive treatment, based on model 2

The results are presented as HRs and 95% CIs
