According to the results of this study, the levels of IL-8, IL-17F, and IL-22 were significantly higher in patients with JIA compared with CG according to the Welch’s t-test (p < 0.05), while the levels of IL-12(p40) and IL-17A were similar to CG (Table 4 and Figure 4). This evidence concerns the gene IL17A and juvenile idiopathic arthritis.
