In univariate binary logistic regression using high-vs-low inflammatory marker concentrations as predictors, with account of strict Bonferroni-corrected threshold (p ≤ 0.001), depression was significantly associated with higher levels of CCL-4, IL-1ra, and IFNγ; the associations with CCL-2, IL-33 and TNF-α were significant below the Bonferroni-corrected threshold (See Table S4 in Supplement). Here, IFNG is linked to major depressive disorder.
