Effect size of mean changes from baseline in the Work Productivity Survey at week 12 (randomized set, observed cases). Effect size (standardized response mean (SRM)) of mean changes from baseline in the Work Productivity Survey (WPS) are presented by the (a) American College of Rheumatology 20% improvement criteria (ACR20) clinical response, (b) American College of Rheumatology 50% improvement criteria (ACR50) clinical response, and (c) Health Assessment Questionnaire – Disability Index (HAQ-DI) minimal clinically important difference (MCID of 0.3) clinical response. SRM (absolute values) thresholds: small, from 0.2 to 0.5 (below the dashed line); moderate, from 0.5 to 0.8 (between the two lines); and large, >0.8 (above the solid line).
