  1. IDS = Inventory of Depressive Symptoms
  2. B = Unstandardized Coefficient
  3. SE = standard error of B
  4. LB = Lower Bound of 95% Confidence Interval for B
  5. UB = Upper Bound of 95% Confidence Interval for B
  6. β = Standardized Coefficient
  7. * p < 0.05
  8. HC = Healthy Control
  9. MDD = Major Depressive Disorder
  10. AAD = Any Anxiety Disorder
  11. MDD + AAD = Major Depressive Disorder + Any Anxiety Disorder
