Immunoglobulin G galactosylation in patients with rheumatoid arthritis (RA) and patients with axial spondyloarthritis (axSpA) in different C-reactive protein (CRP)-level categories. Comparison of agalactosylated immunoglobulin G/monogalactosylated immunoglobulin G (G0/G1) ratios in RA (n = 173) and axSpA (n = 126) categorized by increasing CRP levels. Horizontal lines indicate the median of distribution. p Values derived by Mann-Whitney U test are indicated
