  1. OR odds ratio, CI confidence interval
  2. (a) Adjusted for age, gender, marital status, educational attainment, and having depressive symptoms before baseline survey
  3. (b) Euthymia score was dichotomized by using the median
  4. (c) Euthymia score was divided into four categories by using the quantile
