Patients (%) achieving minimum clinically important differences in fatigue (a), physical function (b), pain (c), and disease activity (d) over 52 weeks (ITT population, LOCF). *P < 0.001 for CZP vs PBO by repeated measures logistic regression. CZP = certolizumab pegol; FAS = fatigue assessment scale; HAQ-DI = health assessment questionnaire - disability index; ITT = intent to treat; LOCF = last observation carried forward; MCID = minimal clinically important difference; MTX = methotrexate; PBO = placebo; PtGA = patient's global assessment of disease activity; VAS = visual analog scale.
