In a new study in the Scandinavian Journal of Gastroenterology, we validated IBD diagnosis date and disease location from the Danish national registries - using records from the regional clinical North Denmark IBD cohort (NorDIBD) as the gold standard.

We report high validity of IBD diagnosis date and of colonic disease in CD and proctitis in UC.
