CRP and Crohn disease: While the correlations were not as strong in Crohn’s disease, urinary GSA significantly correlated with other biomarkers, including ELISA fMPOp (r = 0.25, P = .01), ELISA fMPOa (r = 0.27, P < .01), fCal (r = 0.33, P < .01) and CRP (r = 0.29, P < .01) (Supplementary Figure S10).
