File:Contribution of different osteoarthritis sites to combined age-standardised prevalence, globally and by GBD region, 2020.jpg

English: "Knee osteoarthritis was the largest contributor to combined osteoarthritis age-standardised prevalence in all GBD regions except for central Asia and eastern Europe, where hand osteoarthritis was the largest contributor (figure 3). The proportion of knee osteoarthritis ranged from 34·6% (95% UI 32·2–37·8) in central Asia to 66·2% (63·6–69·2) in east Asia. Hip osteoarthritis was the smallest contributor to osteoarthritis prevalence in all regions except for high-income North America and western Europe, where the contribution of other osteoarthritis was the same or slightly lower. The proportion of hip osteoarthritis ranged from 3·4% (3·1–3·6) in east Asia to 9·5% (8·6–10·3) in high-income North America. The contribution of hand osteoarthritis varied widely by region, with a minimum contribution in east Asia of 21·0% (18·9–22·6) to a maximum contribution in central Asia of 50·0% (47·2–51·4)."
