Fig. 1From: Association between IL-17 and IgA in the joints of patients with inflammatory arthropathiesLevels of IL-17, IL-6 and TGF-β1 in synovial fluids from patients with arthritis. Concentrations of cytokines and frequencies of patients with detectable concentrations of IL-17 (a), TGF-β1 (c), and IL-6 (d) in synovial fluids (SF) of patients with rheumatoid arthritis (RA), spondyloarthritis (SpA) and osteoarthritis (OA). Bars show the mean. **P < 0.01, ***P < 0.0001compared with OA. b Correlation between the IL-17 concentration and DAS28 in SF from patients with RA. e Correlation between the concentrations of IL-6 and IL-17 in SF of RA and SpA patients. The correlations were assessed by the Spearman’s rank correlationBack to article page
