  • Radiographic HOA=at least one joint (DIPJ, PIPJ, IPJ or 1st CMCJ) with KL grade ≥2.

  • * Adjusted for age and sex.

  • CMCJ, carpometacarpal joint; DIPJ, distal interphalangeal joint; EOA, erosive hand osteoarthritis; HAQ, Health Assessment Questionnaire; HOA, hand osteoarthritis; IPJ, interphalangeal joint; KL, Kellgren and Lawrence; PIPJ, proximal interphalangeal joint.
