Mean change from Baseline in DI-HAQ overall score (includes 20 questions assessing physical function in 8 domains - dressing, rising, eating, walking, hygiene, reach, grip, and usual activities). Each question is on a scale of 0-3 mm to measure the ability to perform certain activities (0 = without any difficulty, 1 = with some difficulty, 2 = with much difficulty, and 3 = unable to do so), a component of the ACR criteria by visit. DI-HAQ is derived based on the mean of individual responses not the total of individual questions
