  1. Other covariates (age group, income, region, Charlson comorbidity index, and year of study entry) were adjusted in each survival analysis
  2. CI confidence interval, GI gastrointestinal, HR hazard ratio, MHT menopausal hormone therapy
  3. aAdjusted hazard ratios for mortality in MHT users compared to non-users
  4. bThe incidence rates were calculated per 100,000 person-years
