AGE levels in sera of patients with rheumatoid arthritis and systemic lupus erythematosus, and controls. The levels of Nε-(carboxyethyl)lysine (expressed as equivalents of CEL-crystallin) and 103-E3 antigen (expressed as equivalents of Rib-BSA) were measured in sera of patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), and sera of healthy volunteers as controls (HC). The value 1.0 was assigned to samples with CEL levels of below the limit of ELISA detection with mAb 8-C1, to allow their inclusion in statistical analyses with nonparametric tests. Lines represent medians.
