Distribution of Disease Activity by Clinical, Endoscopic, and Histologic Assessments in Adults with Ulcerative Colitis (n=254)
Distribution of disease activity as assessed by clinical (top triangle) and objective (endoscopy/histology; bottom triangle) on 254 colonoscopies from 179 unique patients with ulcerative colitis. Clinical, endoscopic, and histologic disease activity was quantified by the 2-item patient-reported outcome measure (PRO-2; remission = 0), UC Endoscopic Index of Severity (UCEIS; remission = 0), and Geboes score (remission < 2B.0). Abbreviations: NPV, negative predictive value; PPV, positive predictive value.
