Estimated relationship between the IBDQ total score as a continuous or categorical anchor and the four WPAI-UC components; HRQoL, health-related quality of life; IBDQ, Inflammatory Bowel Disease Questionnaire; WPAI-UC, Work Productivity and Activity Impairment-Ulcerative Colitis. Data from OCTAVE Induction 1 and 2 and OCTAVE Sustain; all treatment groups from each Phase 3 study were pooled for analysis. WPAI-UC component scores are expressed as percentages, with a higher percentage indicating greater impairment and less productivity. The IBDQ total score ranges from 32 to 224 and includes four domains: bowel [total domain score range 10–70], emotional [total domain score range 12–84], social [total domain score range 5–35], and systemic [total domain score range 5–35]. For the total score [range 32–224] and each domain, a higher score indicates a better HRQoL.
