Very good explanation and also funny. I like how he mentioned communicating findings this way won't make the headlines "but the truth rarely does."
Wonderful explanation, and beautiful criticism of the chili fuss. thanks so much

"perhaps telling a story in this way won't lead to such a dramatic headlines but the truth rarely does." After all this mess with COVID and such, one of the coldest lines I've heard.

Individuals with ADHD had an increased risk for dementia and MCI. After adjusting for sex and birth year, a hazard ratio (HR) was 2.92 (95% confidence interval 2.40-3.57) for dementia,
Can you please explain that to me In a very simple words since my English is not good please
Thank you so much. God bless you.
Amazing video - thank you!

Taking sensationalism out of applied statistics is an important job for the wellbeing of the society at large. Sir David Spiegelhalter does it so well. Respect. P.S - You're the reason I became a statistician. Love from India.
This was very concise and explained in a way that is easy to understand. I agree, very helpful, thanks for posting!

This is awesome
Great man you are.
I rarely write comments but this really deserves a thanks!
An amazing video :)
Thank you 🙏
Why does the medical journals continue to publish HRs in studies instead of the absolute risks?
beautiful
Unless I'm not understanding this correctly, one fewer death per 100 in a country the size of the US would amount to 3 million fewer deaths over 10 years. That seems pretty significant to me.
So how is this different frm risk ratio?
Also I want to know how many of the chili eaters developed ulcers.

Can sombody please explain that to me In a very simple words since my English is not good please
that study involved 3,591,689 people of those people who not only had dementia bout 9K also had ADHD HOWEVER that is about only 1 /500TH approximately of the study group who had both conditions. The majority did have dementia BUT DID NOT have ADHD. 0.3% of all the people had ADHD however ONLY 1.5% developed dementia out of that group that means around 98-99% did not give or take. 55,094 (1.5) 100 (1.0) first number is the the ones with dementia and without ADHD the second with. This is out of about 3.5 MILLION people. This hardly proves having the disorder will make you get dementia, given that those without it got it far more cases overall
should be shown in all med schools
You solidify my belief in the published stats that it is all misleading and bonkers
Hazard ratios are totally misleading. It all depends on your y axis. Increase your y axis by 3 times and watch the lines converge. So it is another example of relative vs absolute risk. Relative risk is used by everyone to sell you the results.
0:41 what does he say? 0.66? North.66?
"...who quoted a Hazard Ratio of 0.66..."
The one downvote is from the person who doesn't eat chillis.
