This is so helpful! Thank you! My work involves communicating studies such as this one to the public. I always have a hard time communicating hazard ratios accurately. This helps a lot!
This is fantastic content, I will share with my colleagues, for us non-statisticians that need to appraise the research and understand statistics, this content is gold!
Absolutely marvelous and wonderful way to teach a complicated topic... wish we had more topics from you and stattistics would have been a cakewalk. Thanks very much
Results 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
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.

In the example at all time periods the cumulative deaths in the chilli group was less than in the non chilli group. Moreover, at every time period it looked lower and (from the graph drawn) seemed to be about 66%. All very good. But what about if the deaths in the chilli group in the first year are higher (e.g. some people die of an allergic reaction to chillies) but are lower in all subsequent years? Is it meaningful to talk of a HR in such a case?
"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.

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
Hazard ratios like relative risk is used to "sell you something." A product, a drug or a scientific result. In your example, the real absolute risk reduction was 1%. That was the bottom line. that needed the most emphasis.
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.
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.
I wish you were my teacher, you explained everything so well and presented in such an engaging manner!
😀
This is perhaps the best explanation on Hazard Ratio out there !
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."
incredible. this guy and the folks behind it.
beautifully explained and the results brilliantly disected. Good job!
Exemplary style of presentation!
Clear voice with good intonation variation; natural body gestures and facial expressions :)

Best explanation ever for the Hazard ratio

Wonderful explanation, and beautiful criticism of the chili fuss. thanks so much
Such a great explanation, reminds me of my 1st year uni Maths teacher - wonderful. thanks Prof.
This is fantastic, very clearly explained. Will certainly help me pass my doctor exams. Thank you so much!

I made a post discussing Hazard Ratio giving an example of smoking, but it seems to have disappeared.
WHY?
Why does the medical journals continue to publish HRs in studies instead of the absolute risks?

Fantastic video and examples, thank you!
Great explanation
Excellent. Thank you so much
Thank you so much. God bless you.
this is so helpful, thank you!
Glad it was helpful!
Amazing video - thank you!
Brilliant!
An amazing video :)
Thank you so much for this!
So how is this different frm risk ratio?
Thank you so much sir. Good bless you

Great man you are.
Great video thank you🔥
Also I want to know how many of the chili eaters developed ulcers.
lovely!
This is awesome
Thank you 🙏
0:41 what does he say? 0.66? North.66?
"...who quoted a Hazard Ratio of 0.66..."
Hazard ratios like relative risk is used to "sell you something." A product, a drug or a scientific result. In your example, the real absolute risk reduction was 1%. That was the bottom line. that needed the most emphasis.

Good
beautiful
should be shown in all med schools

You solidify my belief in the published stats that it is all misleading and bonkers
The one downvote is from the person who doesn't eat chillis.
Excellent video and explanation - thank you very much
