There is limited information on international endurance rides and on risk factors for eliminations.
To describe and compare the frequency of occurrence of elimination due to lameness and metabolic reasons from Fédération Equestre Internationale (FEI) endurance rides (≥100 km) during 2008-2011 in all countries and to assess risk factors for elimination due to lameness and metabolic reasons.
Retrospective unmatched case-control study.
Data collected from the FEI website included the following: the country where the ride was held; the year; the result for each horse-rider combination; the number of entries in each class; whether the class was restricted to young riders; and the winning speed. Descriptive data were summarised, and univariable and multivariable logistic regression analyses were performed to assess risk factors for eliminations due to lameness and metabolic reasons.
Between 2008 and 2011, there were 30,741 horse starts at FEI endurance rides of 100-160 km distance in 47 countries. Of all started horses, 30% were eliminated for lameness. Eliminations for metabolic reasons were recorded for 8.7% of all started horses. There was a large range of winning speeds amongst countries (10.2-29.5 km/h). Multivariable analysis revealed that the risk of elimination due to lameness was significantly associated with the country where the ride was held, the year, the distance of the ride and the number of entries. Elimination for metabolic reasons was significantly associated with the country where the ride was held, the year and the number of entries.
Differences existed among elimination rates at FEI endurance rides in different countries (2008-2011). Lameness was the most common reason for elimination globally.
These results provide objective global data on endurance riding that can replace anecdotal information, which has been the base of opinions, decisions and regulations. The Summary is available in Chinese - see Supporting information.
关于国际耐力赛以及淘汰风险因素的信息有限。
描述并比较2008年至2011年期间在所有国家举办的国际马术联合会（FEI）耐力赛（≥100公里）中因跛行和代谢原因而被淘汰的发生率，并评估因跛行和代谢原因而被淘汰的风险因素。
回顾性非匹配病例对照研究。
从FEI网站收集的数据包括：比赛举办的国家；年份；每组骑手与马匹组合的结果；每个级别参赛的马匹数量；该级别是否仅限年轻骑手参赛；以及获胜速度。对描述性数据进行总结，并进行单变量和多变量逻辑回归分析，以评估因跛行和代谢原因而被淘汰的风险因素。
2008年至2011年期间，在47个国家举办的100 - 160公里的FEI耐力赛中，共有30741匹马参赛。在所有参赛马匹中，30%因跛行被淘汰。所有参赛马匹中有8.7%因代谢原因被淘汰。各国的获胜速度差异很大（10.2 - 29.5公里/小时）。多变量分析显示，因跛行被淘汰的风险与比赛举办的国家、年份、赛程距离和参赛马匹数量显著相关。因代谢原因被淘汰与比赛举办的国家、年份和参赛马匹数量显著相关。
不同国家（2008 - 2011年）FEI耐力赛的淘汰率存在差异。跛行是全球最常见的淘汰原因。
这些结果提供了关于耐力赛的客观全球数据，可取代一直作为观点、决策和规则依据的传闻信息。中文摘要见补充信息。
