Relative importance of urgency status or Mayo subscores to variation in IBDQ measures at Week 12. Partial R² values were calculated from an ANCOVA model that includes bowel urgency, rectal bleeding, or stool frequency status, to compare the proportion of variation in QoL gained from the addition of each symptom into the model. Brighter green indicates a stronger contribution while red indicates a weaker contribution. Abbreviations: ANCOVA, analysis of covariance; BL, baseline; IBDQ, Inflammatory Bowel Disease Questionnaire; QoL, quality of life; RB, rectal bleeding; SF, stool frequency; W12, Week 12.
