  1. For each diagnosis, a Wilcoxon rank sum test was performed to compare the MDD patients with those without MDD
  2. 1 US dollar equals approximately 1200 Korean won
  3. *p < 0.05; **p < 0.001; ***p < 0.0001
  4. aPatients without MDD were matched with patients with MDD by propensity score based on demographic characteristics, i.e., age, sex, and the type of National Health Security program enrolled
  5. ICD International Classification of Diseases, MDD major depressive disorder, PS propensity score, Q1 25th percentile, Q3 75th percentile, Rx prescription
