As part of the screening visit, this study collected the patient's history of CD. Some information was provided directly by the patient, and other information was obtained from the subject's medical records. MHCAT was used to delineate between more general CD questions and those that pertain to extra-intestinal manifestations (EIM). MHTERM was assigned by the sponsor using the appropriate MedDRA Lowest Level Term (LLT), when available. MHDECOD was reported as the MedDRA Preferred Term. Note: Upper gastrointestinal CD is currently not as MedDRA LLT. If required, sponsors may request new terms be added to MedDRA (see https://www.meddra.org/how-to-use/change-requests).
