- Group 1 definition Diagnostic criteria applied to define the specific condition / phenotype represented in the case (exposed) group
- The adenoma and carcinoma patients were diagnosed by colonoscopic examination and histopathological review of biopsies. Postoperative patients were classified as having NDA or CIT by follow-up surveillance colonoscopy and biopsies
