Sometimes John Ioannidis just makes me laugh. 😀
In the slide below, Ioannidis discusses age-specific IFR (infection fatality rate), i.e. what proportion of SARS-CoV-2-infected people die of the disease COVID-19 at various ages.
22:23 - 23:18:

Here's the work Ioannidis is likely referring to:
Axfors (Ioannidis is the lead author)
ncbi.nlm.nih.gov/pmc/articles/P…
Levin (from @GidMK + @BillHanage)
link.springer.com/article/10.100…
O'Driscoll

CDC

Ioannidis says his Axfors estimates mostly agree with O'Driscoll:
from 23:04
Yet experts noted for around year that his Axfors estimate is a low outlier.
So what's going on here?

O'Driscoll et al. leave out nursing home deaths, while Levin + CDC include them.
Including nursing home deaths increases IFR in older groups, which is one of the main reasons why CDC + Levin are higher than O'Driscoll.

So Ioannidis should compare O'Driscoll (purple) to his *blue* Axfors results that *exclude* nursing home deaths.
But he compares purple to his *red* Axfors results that *include* nursing home deaths.
Thus, he conceals his work being an outlier. 🤦♂️

John Ioannidis either:
- misremembered
- didn't read O'Driscoll et. closely
- willfully misled his audience
In any event, @GidMK was again more forthcoming than Ioannidis. Makes it even more ridiculous that Ioannidis smeared @GidMK multiple times.

And, of course, later research supported @GidMK's and @hanage's Levin / CDC results that Ioannidis objected to.
That isn't just my interpretation; that's what the authors of the research state:

This is not the first time Ioannidis has criticized that paper by distorting other research. It's just the first time I've seen him be so blatant + brazen in his distortions.

Ioannidis also says that the papers agree IFR was "very low" until about age 50.
Well, "low" is relative. Compared to other causes of death, it wasn't low. The Levin paper was pretty explicit on that, as were others.

The CDC previously cited another age-specific IFR estimate from @C_Althaus, that largely matched Levin + was larger than Ioannidis' estimate.
Ioannidis left it out, of course

Ioannidis' image also left out the results from Neil Ferguson's team at Imperial College, which again matched Levin.
When he *conveniently* leaves stuff out, it helps conceal the fact that his results are a low outlier.

Axfors update is out.
Ioannidis knew O'Driscoll showed a higher IFR than Axfors results. So he was just being misleading when he said otherwise in the video, as usual.

The Axfors update even adds Imperial College's analysis (ICCRT; see part 11/U), again illustrating how much Ioannidis' Axfors results are a low outlier.
Remember, he did a misleading comparison of orange vs. red, when it should be orange vs. blue.

Several studies present observational evidence of tremendous under-counting of COVID-19 deaths in India, contradicting Ioannidis' model-based claim.

Researchers keep getting age-specific infection fatality rates larger than Ioannidis' work. Amazing how he can still claim his work isn't a low outlier.

Of course, the usual COVID-19 minimizers like it.
