Weight loss, any loss in weight; no change, no change in weight; weight gain, any gain in weight.
↵* Difference in cartilage thickness between follow-up and baseline.
↵† Annual rate of change (%/year) = (change in cartilage thickness/baseline cartilage thickness)×100%.
↵‡ Standardised response mean (mean/SD of change).
