Major clinical response=ACR70 ≥6 months.
Number of patients with non-missing ACRn assessments for all groups was 248.
Analysis-of-variance model adjusted for stratification factors (RF status, region) (adjusted mean changes shown in the table); Cochran–Mantel–Haenszel test was used for categorical variables, non-responder imputation was used for ACR major clinical response and EULAR response variables and last observation carried forward was used for DAS28 LDA, DAS28 remission and HAQ-DI.
ACRn, American College of Rheumatology index of improvement in RA; DAS28, Disease Activity Score in 28 joints; EULAR, European League Against Rheumatism; HAQ-DI, Health Assessment Questionnaire-Disability Index; LDA, low disease activity; MTX, methotrexate; RF, rheumatoid factor.
