Munjiza reported that IL-6 was positively correlated with total CTQ (r = 0.379, p<0.01), physical neglect (r = 0.323, p<0.01), emotional abuse (r = 0.382, p<0.01), and physical abuse (r = 0.320, p<0.01) in an unadjusted analysis limited to participants with MDD only [64]. Here, IL6 is linked to major depressive disorder.
