Core Tip
Core tip: According to our study, the Montreal is a reliable classification system for phenotypes in inflammatory bowel disease, except for disease severity in ulcerative colitis. The inter-observer agreement for scoring Crohn’s disease severity was moderate. This highlights the need for accurate medical reporting and the use of additional parameters to define and classify disease severity. Such alternations are necessary to ensure high-quality data in multicentre prospective data collections.
