Bold represents statistical significance.
Model 1: adjusted for age, gender, smoking status, alcohol drinking, and BMI. Model 2: adjusted for age, gender, smoking status, alcohol drinking, BMI, TC, TG, HDL-C, LDL-C, ALT, TB, WBC, and HGB.
ALT, alanine aminotransferase; BMI, body mass index; CI, confidential interval; HDL-C, high-density lipoprotein cholesterol; HGB, hemoglobin; HR, hazard ratio; LDL-C, low-density lipoprotein cholesterol; TB, total bilirubin; TC, total cholesterol; TG, triglyceride; WBC, white blood cell count.
