Serum levels of Gal-9 and sTIM-3 in IgG4-RD. The comparison of serum levels of Gal-9 and sTIM-3 among IgG4-RD patients (n = 59), RA patients (n = 13), and healthy controls (n = 37). a Serum levels of Gal-9 in IgG4-RD and RA patients were significantly higher compared to those in healthy controls. b Serum levels of sTIM-3 in IgG4-RD patients and RA patients were significantly higher compared to HCs. The Kruskal-Wallis test was used for continuous variables for comparisons among the three groups. Post hoc pairwise analyses between the two groups were performed by the Games-Howell test
