  1. Results are shown for all, and separately for men and women. # Nominal p value.
  2. All associations are adjusted for age, sex (in full sample analyses) and blood cell counts. HDRS_1= Question 1 in Hamilton Depression Rating Scale (HDRS): DEPRESSED MOOD (sadness, hopeless, helpless, worthless), HDRS_3= Question 3 in HDRS: SUICIDALITY, BDI_01= Question 1 in Beck’s Depression Inventory (BDI): Sadness, BDI_09= Question 9 in BDI: SUICIDALITY.
  3. *Significant difference, p < 0.05.
