  • * OR (95% CI) and p values from corrected univariate analyses (separate GEE models adjusted for age and sex).

  • Multivariate analyses (one combined GEE model after backward selection of variables from the separate models, adjusted for age and sex).

  • Joints with synovitis grade 0–1 serve as reference.

  • BMLs, bone marrow lesions; CL, collateral ligament; GEE, generalised estimating equations.
