Fig. 4From: Prostaglandin E-major urinary metabolite versus fecal immunochemical occult blood test as a biomarker for patient with ulcerative colitisInfluence of a long disease duration of ulcerative colitis (UC) on the correlation between urinary/fecal biomarkers and Mayo endoscopic subscore (eMayo). Scatter plots of (a) eMayo vs. prostaglandin E-major urinary metabolite (PGE-MUM), and (b) eMayo vs. fecal immunochemical occult blood test (FIT) in patients with UC with disease duration of < 5 years. Scatter plots of (c) eMayo vs. PGE-MUM and (d) eMayo vs. FIT in patients with UC with a disease duration of ≥5 yearsBack to article page
