  3. ‡ : HR: adjusted for age, gender, education, drinking and smoking
  4. §: Age-specific mortality rate in Taiwan (annual per 100,000) was shown here instead of directly calculating mortality from the cohort because the number of TB deaths in this cohort followed up even for 14 years was too small to be stable.
