| JSN, joint space narrowing. Joint space narrowing and osteophyte were defined based on a radiographic grade ⩾1 from the scale 0–3; HN, Heberden’s nodes were graded based on the scale 0–2; aOR, adjusted odds ratio by age (<65 years v ⩾65 years), sex (female v male), body mass index (normal (<25 kg/m2) v overweight (⩾25 kg/m2)). | |||||||
