Time frame: From Baseline of the preceding double-blind study to Completion/Withdrawal of the open-label study (up to approximately 6.8 years)
The HAQ-DI assesses the degree of difficulty experienced in eight domains (Dressing and Grooming, Arising, Eating, Walking, Hygiene, Reach, Gripping, Other Activities) of daily living activities using 20 questions. The HAQ-DI is calculated by summing the domain scores and dividing them by the number of domains. It ranges from 0 (no difficulty) to 3 (unable to do). Negative values indicate an improvement from Baseline to the Post-Baseline Visit with larger negative values showing a better improvement.
