Increased IL-33 in Synovial Fluid and Paired Serum Is Associated with Disease Activity and Autoantibodies in Rheumatoid Arthritis

<table>Interleukin 33 (IL-33) levels in synovial fluid (SF) from RA patients. RA patients were categorized into 3 groups according to the Disease Activity Score based on ESR. Low: low activity group; Mod: moderate activity group; High: high activity group. Symbols represent individual samples. Horizontal bars represent median IL-33 levels.</table>
