Fig. 4From: Circulating mature granzyme B+ T cells distinguish Crohn’s disease-associated axial spondyloarthritis from axial spondyloarthritis and Crohn’s diseasePlasma IFN-γ and IL-6 are elevated in subjects with CD-axSpA. Plasma from our cohort was evaluated for circulating cytokines by a multiplex ELISA. Symbols represent individual values of (a) IFN-γ and (b) IL-6 while bars are the group mean ± SEM in pg/ml. * denotes P < 0.05 determined by Mann-Whitney tests. Values below the limit of detection for the assay were not plottedBack to article page
