Increased IL-33 in Synovial Fluid and Paired Serum Is Associated with Disease Activity and Autoantibodies in Rheumatoid Arthritis
Figure 1
IL-33 levels in serum and SF samples in 54 RA patients were measured simultaneously. The levels in SF (median 15.24 pg/mL) were lower than those in sera (median 31.64 pg/mL (a)). A significant correlation between two groups was estimated by Spearman’s correlation test (, (b)).
