Stability of HAQ-DI changes during therapy. Continued achievement of HAQ-DI improvement criteria at months 12 and 24 was evaluated in patient subgroups based on HAQ-DI improvement at month 6. HAQ-DI-dcrit improvement was defined as HAQ-DI change from baseline ≥0.68, small improvement as ≥0.22 to < 0.68, and no improvement as < 0.22. Differences in patient numbers from Table 3 are due to the absence of HAQ-DI data in some patients. HAQ-DI Health Assessment Questionnaire-Disability Index, HAQ-DI-dcrit critical difference for change beyond random variation in the HAQ-DI (decrease ≥0.68 from baseline)
