Serum CD74 levels in patients with RA and CS. Serum CD74 levels in patients with RA (n = 101) and CS (n = 9) (a). Serum CD74 levels of RA patients stratified using the DAS28-ESR: remission (<2.6, n = 27), low activity (≥2.6 < 3.2, n = 16), moderate activity (≥3.2 < 5.1, n = 35), high activity (≥5.1, n = 23) (b). Data presented as median (p5–p95). Statistical comparisons between groups were determined using the Mann–Whitney U (AR vs. CS) and Kruskall–Wallis (DAS28) tests. * p < 0.05; ** p < 0.01. RA: rheumatoid arthritis; CS: control subjects; DAS28, disease activity score 28.
