Numbers are percentages (range 0–100%) with 95% CI in parentheses. Subpopulation with hand pain: having pain of the hands ≥1 day during the last month; subpopulation with symptomatic radiographic hand OA: meeting the criteria for hand symptoms and at least one joint in the DIPJs, PIPJs or first IPJs or the first CMCJ with a Kellgren–Lawrence score ≥2; IPJs: including DIP, PIP or first IPJ. EOA: erosive OA; RHOA: radiographic hand OA.
