Association between the FOXO3A rs12212067 genotype and CD disease characteristics based on the Montreal classification [27].

For each variable, the number of patients included is given.1Disease behaviour was defined according to the Montreal classification. A stricturing disease phenotype was defined as presence of a stenosis without penetrating disease. The diagnosis of stenoses was made surgically, endoscopically, or radiologically (using MR enteroclysis).2Immunosuppressive agents included azathioprine, 6-mercaptopurine, methotrexate, infliximab, and/or adalimumab.3Only surgery related to CD-specific problems (e.g., ileocecal resection, fistulectomy, colectomy, and ileostomy) was included.Association between the FOXO3A rs12212067 genotype and CD disease characteristics based on the Montreal classification [27].
