Correlation between changes in ratio of agalactosylated to monogalactosylated N-glycans in serum (sG0/G1) and 28-joint Disease Activity Score utilizing C-reactive peptide. Differences reported are between baseline and 3-month visits. Each point represents an individual patient. Plots at right depict improvement (decrease) in Disease Activity Score (DAS) comparing patients in whom the sG0/G1 either increased or decreased appreciably (> 0.1 U) over the interval studied. (A) Autoimmune Biomarkers Collaborative Network (ABCoN). (B) Nested I.
