CDAI remission
時間枠:Week 12
|
Crohn's Disease Activity Index (CDAI) is a research tool used to quantify the symptoms of patients with Crohn's disease. It is based on: number of loose stools, abdominal pain, general well-being, extraintestinal complications, antidiarrheal agents used in the previous 7 days, abdominal mass felt on palpation, hematocrit and body weight |

Endoscopic response
時間枠:Week 12
