IL37 and type 2 diabetes mellitus: Multinomial logistic regression analysis (CTRL was the reference category) showed that elevated levels of IL‐39 were significantly associated with T2DM (OR = 1.30; 95% CI = 1.19–1.42; p < .001), while IL‐37 did not show this association (OR = 1.01; 95% CI = 0.99–1.02; p = .558) (Table 2).
