- Note: The Mantel-Haenszel estimate and corresponding CIs for the RD were estimated by the non-parametric analysis of covariance method using the SAS NParCov4 macro with strata determined by IXRS values of the stratification factors geographic region (Europe, North America combined with Asia Pacific) and prior biologic use and adjustment for baseline covariates (tender joint count, swollen joint count, Subject’s Global Health Assessment, Investigator’s Global Health Assessment, Subject’s Assessment of Disease-related Pain, HAQ-DI, C-reactive protein, age, use of oral corticosteroid, use of non-steroidal anti-inflammatory drugs, body mass index categories of < 25, 25–30, and ≥ 30, and methotrexate dose)
