Contrary to the results obtained for IL-2, reduced serum IL-10 levels maintained a significant but negative association with both DSM-5 scores (r=-0.300, p = 0.045) and GAD-7 scores (r=-0.315, p = 0.039), implicating that altered IL-10 levels are linked to GAD development or pathogenesis. Here, IL10 is linked to generalized anxiety disorder.
