The IL-33 expression of gout patients with tophi (median 154.0 pg/mL: 57.9–589.1) or not (median 185.7 pg/mL: 31.3–741.3) (p = 0.635) and with hypertension (median 150.7 pg/mL: 31.3–741.3) or not (median 196.7 pg/mL: 71.7–614.0) (p = 0.804) did not show a significant difference (Figures 2(a) and 2(b)). Here, IL33 is linked to gout.
