Validation of ulcerative colitis and Crohn's disease and their phenotypes in the Danish National Patient Registry using a population-based cohort.

CONCLUSIONS: The DNPR has good validity and reliability in identifying patients with CD and UC, and defining the age of patients at diagnosis. However, categorising IBD patients according to the Montreal Classification should not be carried out using DNPR data in their current form, except when identifying CD patients with perianal disease.
