🚨 Significant news in cases of Caster Semenya & other women athletes banned by @WorldAthletics from events ranging from 400m to one mile.

A @BJSM_BMJ correction has been made to a 2017 paper authored by two WA (then IAAF) employees. /1

‘In the correction… WA now admits that its claims of a causal relationship between testosterone levels and athletic performance among female athletes in the restricted events was incorrect.’

These claims prevented @caster800m & others from competing at #Tokyo2020. #LetHerRun /2

.@RogerPielkeJr continues in his article: “The WA correction offered… provides a very public test of the integrity of World Athletics. [It] chose to base its 2018 regulation on a set of scientific claims. It now admits that those claims were wrong and potentially misleading.” /3
