  • a Cox proportional hazard models were used to estimate HRs and 95% CIs.

  • b Model 1: adjusted for age, sex, smoking status, alcohol intake, regular exercise, BMI, LDL cholesterol, HDL cholesterol, and triglycerides. Model 2: model 1 plus adjustment for hypertension, diabetes, history of heart disease, and history of stroke. Model 3: model 2 plus fatty liver.
