  1. Presented are the prevalence rates and 95% confidence intervals (95%CI) for site-specific and non-specific OA per country and per definition used. 95%CI was calculated as: p ± 1.96 * SE in which SE = √ (p (1 - p)/n) and p = proportion. Results were weighted for age and sex in the European Standard Population as of January 1, 2001, and stratified for age.
