IL6 and generalized anxiety disorder: While a trend of positive association was observed between higher GAD scores (Fig. 1D; (β^ = 0.03 (− 0.02, 0.08); p = 0.21)) and PSS scores (Fig. 1F; (β^ = 0.01 (− 0.01, 0.03); p = 0.31)) and higher levels of IL-6, neither of these associations were statistically significant.
