Post-hoc pairwise analysis showed that IL-6 levels were significantly higher in the MDD/SA group compared to the MDD/NS group (mean diff = 0.44, p = 0.0161); but no group differences were found between MDD/SA and HC (mean diff = 0.40, p = 0.0509) nor between MDD/NS and HC (mean diff = −0.05, p = 0.9586). The gene discussed is IL6; the disease is major depressive disorder.
