The percentage of athletes with Therapeutic Use Exemptions (TUEs) competing in elite sport and the association with winning medals has been a matter of speculation in the absence of validated competitor numbers. We used International Olympic Committee (IOC) and World Anti-Doping Agency (WADA) data to identify athletes competing with TUEs at five Olympic Games (Games) and a possible association between having a TUE and winning an Olympic medal.
We used the IOC's competition results and WADA's TUE database to identify the number of TUEs for athlete competitions (ACs, defined as one athlete competing in one event) and any associations with medals among athletes competing in individual competitions. We calculated risk ratios (RR) for the probability of winning a medal among athletes with a TUE compared with that of athletes without a TUE. We also reported adjusted RR (RR) controlling for country resources, which is a potential confounder.
During the Games from 2010 to 2018, there were 20 139 ACs and 2062 medals awarded. Athletes competed with a TUE in 0.9% (181/20 139) of ACs. There were 21/2062 medals won by athletes with a TUE. The RR for winning a medal with a TUE was 1.13 (95% CI: 0.73 to 1.65; p=0.54), and the RR was 1.07 (95% CI: 0.69 to 1.56; p=0.73).
The number of athletes competing with valid TUEs at Games is <1%. Our results suggested that there is no meaningful association between being granted a TUE and the likelihood of winning a medal.
在缺乏经过验证的参赛选手数量的情况下,有治疗用药豁免(TUE)的运动员在精英体育赛事中的参赛比例及其与获得奖牌之间的关联一直是人们猜测的话题。我们使用国际奥林匹克委员会(IOC)和世界反兴奋剂机构(WADA)的数据,在五届奥运会(奥运会)中确定了使用 TUE 参赛的运动员人数,以及 TUE 与获得奥运会奖牌之间的可能关联。
我们使用国际奥委会的比赛结果和世界反兴奋剂机构的 TUE 数据库,确定了运动员比赛中 TUE 的数量(AC,定义为一名运动员参加一项比赛),以及在个人比赛中参赛运动员获得奖牌的任何关联。我们计算了 TUE 运动员与无 TUE 运动员获得奖牌的概率之间的风险比(RR)。我们还报告了在控制国家资源(这是一个潜在的混杂因素)后调整的 RR(RR)。
在 2010 年至 2018 年奥运会期间,有 20139 个 AC 和 2062 枚奖牌。有 181 名运动员在 0.9%(181/20139)的 AC 中使用 TUE 参赛。有 21 枚奖牌被使用 TUE 的运动员获得。TUE 运动员获得奖牌的 RR 为 1.13(95% CI:0.73 至 1.65;p=0.54),RR 为 1.07(95% CI:0.69 至 1.56;p=0.73)。
在奥运会上使用有效 TUE 参赛的运动员人数<1%。我们的结果表明,获得 TUE 与获得奖牌的可能性之间没有明显的关联。
