  1. Model 1: non-adjusted.
  2. Model 2: adjusted for age and sex.
  3. Model 3: adjusted for age, sex, body mass index, income, smoking, drinking, hypertension, and dyslipidemia.
  4. Model 4: adjusted for age, sex, body mass index, income, smoking, drinking, hypertension, dyslipidemia, fasting glucose, chronic kidney disease, diabetes mellitus duration (< 5 vs. ≥ 5 years), oral hypoglycemic agents (< 3 vs. ≥ 3), and insulin use.
  5. TB: tuberculosis; PY: person-year; IR: incidence rate; Ref.: reference; METs-min/week: metabolic equivalent task minutes per week.
