Evaluation of the Risk of Relapse in Ulcerative Colitis According to the Degree of Mucosal Healing (Mayo 0 vs 1): A Longitudinal Cohort Study

Background and aims:Mucosal healing in ulcerative colitis (UC) has become a common endpoint in most clinical trials and a relevant therapeutic goal in clinical practice. Despite important differences between endoscopic Mayo scores 0 and 1, both scores are considered as mucosal healing in most important trials. The aim of the present study was to evaluate the risk of relapse in UC patients according to the degree of mucosal healing (endoscopic Mayo scores of 0 and 1).
