Validation of date of diagnosis and disease location of inflammatory bowel disease in the Danish National Patient Registry and the Danish Pathology Registry using a regional cohort
The date of IBD diagnosis in the NPR showed high validity. IBD location could be inferred <i>via</i> pathology codes for approximately 60% of patients with IBD, with high validity for colonic disease in CD and proctitis in UC. These findings are useful in future epidemiological studies in IBD.
