Relationship between soluble Mer (sMer), soluble Tyro3 (sTyro3), soluble Axl (sAxl), and Gas6 and cytokine levels in the synovial fluid and erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) in the blood of rheumatoid arthritis (n = 20). Data are presented as Pearson r value (r) and P value for each correlation. ^∗P < 0.05; ^∗∗P < 0.01; and ^∗∗∗P < 0.001.
