Correlations between WPAI domain scores and DAS28-CRP at week 12/ET. Except for “daily activity impairment,” only full-time paid workers and part-time paid workers were included (not homemakers). At week 12/ET, last observation carried forward was used for missing WPAI scores. The Pearson (r) correlation coefficients assessed the relationships between WPAI domains (absenteeism, presenteeism, loss of work productivity, and daily impairment) and clinical response (DAS28-CRP). A 95% prediction ellipse is displayed on each plot. DAS28-CRP, 28-joint disease activity score based on C-reactive protein. ET early termination, WPAI Work Productivity and Activity Impairment
