  1. Incidence is per 1000 person-years follow-up.
  2. Multivariate model 1 is adjusted for age, sex, body mass index, waist circumference, smoking status, alcohol consumption, regular physical activity, income level, ɣ-glutamyl transferase, hypertension, diabetes mellitus, dyslipidemia, and chronic kidney disease.
  3. Multivariate model 2 if further adjusted for death as a competing risk.
  4. IFG impaired fasting glucose, SCA sudden cardiac arrest.
