Bar graphs illustrate the serum concentration of IL-17 A (A) and IL-25 (B) in the healthy subjects and knee osteoarthritis patients with WOMAC < 40 and VOMAC ≥ 40. Data are shown as mean ± SD and an independent sample t-test was used to compare the groups (ns; non-significant, *P < 0.05, **P < 0.01, ****P < 0.0001)
