Description of the different dimensions. 1 = mobility, 2 = self-care, 3 = usual activities, 4 = pain, and 5 = anxiety/depression at baseline (panel A), at 2-year follow-up (panel B), and at long-term follow-up (panel C). There were 3 alternative answers for each dimension, according to the degree of severity: no problems, moderate problems, or severe problems.
