John Ioannidis published an article defending his low estimate of COVID-19's fatality rate.
It contains so many distortions that I'll try something I've never done on Twitter for a paper:
Go thru distortions page-by-page.
This will take awhile. 😑

Some context:
Infection fatality rate, or IFR, is the proportion of people infected with the virus SARS-CoV-2 who die of the disease COVID-19.
There are many IFR estimates, including some from Ioannidis.

Seroprevalence studies (serosurveys) measure antibody levels to estimate the number of infected people.
Dividing COVID-19 deaths by that number of infected people gives a seroprevalence-based IFR.

One can over-estimate seroprevalence (+ thus under-estimate IFR) by measuring seroprevalence in a sample that does not represent the general population, and then extrapolating that sample to the general population.
Ioannidis does this.

Ioannidis defends his use of non-representative samples.
But his defense fails. For example:
- non-representative samples are still unreliable
- he uses non-representative samples even in hard hit areas

- he could just wait for representative sampling in less hard hit areas
- areas often looked less hard hit because they under-estimated COVID-19 deaths, so including them under-estimates IFR

So in this thread, *keep this in mind*:
Ioannidis has to keep non-representative samples in, because representative samples show an IFR incompatible with his position.
That's his main game, + what he often distracts from

#3 is worst because it extrapolates from inaccurate samples, under-estimating IFR. Yet that's what Ioannidis chooses to do + uses Bobrovitz for.
#1 makes sense; that's what "Meyerowitz-Katz" (@GidMK) did. But if you must have data for policy or planning, #2 can work.

You could survey people in 1 building.

I have seen scientists address criticism of their work from Twitter, usually by responding to the general criticism without mentioning the tweets.
I have *never* seen a scientist evade criticisms of their work, while naming Twitter accounts, their number of tweets, etc.

In doing this, Ioannidis has tacitly admitted he can't rebut criticism of his work.
Are any of the people who whined about negative tone of Ioannidis' critics going to call him out for this?
Of course not. 🙂

And unsurprisingly, Ioannidis extends his evidence-free ideologically-motivated smears to Ferguson et al.'s team at Imperial College, without ever admitting they did not over-estimate IFR.

So for Ioannidis' defenders, that's what you're left with:
An ideologue who makes mathematically impossible claims that suit his ideology, and names Twitter accounts in his paper since he can't rebut their critiques.

And there's Ioannidis' not so subtle attempt to encourage his fans to dox me.

Are any of the people who incorrectly whined about Ioannidis (supposedly) being "silenced", going to call him on that?
Of course not. 😑

Also, this was not a one-time lapse in judgment on Ioannidis' part. He's done this before in the same journal.
So Ioannidis was editor-in-chief at European Journal of Clinical Investigation for a decade, and it's now his venue for attacking people

Found the PubPeer thread on Ioannidis' paper, for those who want to defend it or critique it (I don't post on PubPeer, nor do I have an account there):
