Plasma concentrations of soluble CD18 (sCD18) in patients with spondyloarthritis (SpA) at the time of inclusion and at the 4-year follow-up and healthy controls (HCs). The median values of plasma sCD18 were 639.7 mU/mL (interquartile range 514.3-726.8 mU/mL) for patients with SpA at the time of inclusion, 606.1 mU/mL (interquartile range 458.4-691.5 mU/mL) for patients with SpA at the 4-year follow-up, and 767.2 mU/mL (interquartile range 628.1-839.7 mU/mL) for HCs. Bars indicate median and interquartile range. ***P <0.001, ****P <0.0001.
