CD20 Immunohistochemistry (IHC) correlates with B cell gene-set score in a replication rheumatoid arthritis (RA) patient cohort. Representative CD20 IHC (brown staining) is shown for synovial samples with a high or low B cell gene-set score with low (A, B respectively) and high (C, D respectively) magnification. B cell gene-set scores were also plotted against CD20 IHC scores and the P-value for Spearman rank correlation coefficient is indicated (E).
