Relationships between the serum levels of checkpoint molecules and IgG subclass in IgG4-RD. a, b The serum levels of Gal-9 showed a positive correlation with IgG whereas not a significant correlation with IgG4. c, d The serum levels of sTIM-3 showed a positive correlation with IgG whereas not a significant correlation with IgG4. All correlations were determined using Spearman’s rank correlation test. The lines shown are based on simple linear regression
