[1]
Measure Description: The IBDQ is an instrument used to assess quality of life in participants. It includes 32 questions on 4 domains : Bowel Systems (10 items), Emotional Function (12 items), Social Function (5 items), and Systemic Function (5 items). A total IBDQ score is calculated by summing the scores from each domain; the total IBDQ score ranges from 32 to 224, with lower scores reflecting worse health.

[1]
Measure Description: The Mayo score is sum of 4 sub-scores (i.e., stool frequency, rectal bleeding, endoscopic findings (excluding friability at grade 1), and physician's global assessment); each rated on a scale from 0 to 3, with higher scores indicating more severe disease. The total Mayo score value ranges from 0 to 12. Higher values represent worse disease.

Measure Description: Nancy Histological Index (NHI) classifies histologic status, a score from 0 to 4. Grade 0= no histological findings, grade 1= no acute acute inflammatory infiltrate, grade 2= acute inflammatory cells infiltrate and no ulceration 3= acute inflammatory cells infiltrate and no ulceration 4= ulceration. The most severe observation across all segments is used for the final NHI score. A higher score indicates more severe disease.
