Overall score was computed as the sum of domain scores and divided by the number of domains answered. Total possible score range 0 (least difficulty) and 3 (extreme difficulty), where higher scores indicate more difficulty while performing daily living activities. | Baseline, Months 2, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60 and 63 |
