  1. Statistically significant (p ≤ 0.05) results indicated in bold type.
  2. ¥ Results further adjusted for diagnosed OA at all sites, pain at all sites, presence of rheumatoid arthritis and leg strength.
  3. ϒResults further adjusted as for the analyses for Baseline to Phase 2, but without Diagnosed OA as this was not asked at Phase 3.
  4. 5 year follow up data includes data collected at Phase 1, 2 and 3 and is not limited to participants with complete data.
  5. Radiographs not included as they were only collected at Phase 1.
