It seems that with the revelation of CTE there sadly seems to be some athletes that may be attributing what they are going through to CTE when that might not be the case. This shows that we need to try and discover some sort of detection before a person is dead to help them either A) deal with the changes that are going to affect them or B) give them the peace that this is not happening to them.
A notable missing sport was the NHL. It would be interesting to see what the NHL data shows and even the soccer given the repeated headers that occur in that sport.
This study is empirical garbage. That doesn't mean the claim is false, but they do not have the statistical power to detect the effect that they're claiming.
Thankfully, there just aren't enough suicides to do a study like this properly.
Spicy take, I like it!
Reminds me of the Pfizer study that said their vaccine reduces children's risk of covid by 300% because the treatment sample had 1 case (out of 2,000) and the control sample had 4 cases.
I was talking to a doctor the other day and he confirmed some of my priors that the standards for medical studies are actually quite low, and most doctors don't care because they just want lines on their CV (like everyone else)
Almost every other discipline has low standards for statistical analysis.
I don't know if you've ever tried to work with these kinds of low probability events, but this claim was an immediate red flag to me.
I'm actually not well versed in the statistics of extremely low probability events, but it was a red flag for that Pfizer study to me as well. I'm pretty sure you can't just naively apply the standard calculation for standard errors when event counts are that low.
I've only dabbled and never came up with results I was happy with, but you're right about the standard errors. The distributional assumptions are more important when you can't count on the Central Limit theorem applying.
I wish they were more clear about exactly what they did, but I think the authors might not know themselves, as they just reference the STATA package they jammed everything into.
Did you dabble because of a specific project you were working on? Or just out of theoretical interest?
A specific project related to mass shootings. We really need a lot more of those if we want to understand them.
Interesting. One of my department colleagues writes on that topic
Hopefully some of the innovations like the guardian caps and Q-collar will help mitigate some of the brain injuries.
Q-Collar!
110% agree. The part about a growing part of NFL players thinking they have CTE when that might not have been the case is a disturbing trend.
The next step should be a collective effort involving leagues medical researchers and players associations to develop methods for identifying and treating the spectrum of symptoms earlier and more effectively. Players need reassurance not just through mental health resources but by knowing there is a proactive system in place that is constantly working to separate fear from fact and to provide tangible medical solutions to real medical problems. Only then will we begin to change the trajectory of this issue in a meaningful way.
