There is a significant bias here in that its 99% of NFL players brains * which have been donated to the NFL *.
But honestly even if you could peek into every NFL players brain, I'm sure the likely incidence after 4-5 years of playing would be orders of magnitude greater than whats found in the general population.
- smeyer 9y agoThere's obviously a bias, but the mentioned study claimed that even if the rate of CTE were 0% among brains not donated to the study, their sample would still be large enough to indicate a significant deviation from the general population.
- learc83 9y agoThat is a bias. But it's also almost 10% of all NFL players that died during the study period.
- yk 9y agoYes, however the NYT mentioned yesterday, even if the brains are the only cases of CTE, then the incidence rate among players would still be vastly higher than in the general population.
