      3/n I should say at the outset here - the only personal comment I would like to make about Professor Ioannidis is that he is a very smart man who I respect tremendously I will, however, examine the paper, because I think that is what science is all about

      4/n At first glance, and indeed on deeper reading, it is clear that very little has changed from my previous looks into the paper

      5/n The methodology is still the same, and the eventual conclusion remains that the median IFR of COVID-19 is 0.27% (originally he estimated 0.26%)pic.twitter.com/kBhIWCEUAL

      6/n The author then concludes that the IFR "tended to be much lower than estimates made earlier in the pandemic", which is odd because his own estimates made earlier in the pandemic (in May) were...lowerpic.twitter.com/7awIA4gEoW

      7/n Indeed, as we can easily see, the resulting low IFR is simply a consequence of the low quality of the review itself and has very little to do with when the estimates were made

      8/n For example, the review does not adhere to PRISMA guidelines (the most basic recommendations for reviews of this kind) which is very strange given that Prof Ioannidis himself is a co-author on the original PRISMA statementpic.twitter.com/fgwRh67bkL

      9/n This has lead to a problematic situation, where there is no rating for study quality, publication bias, and indeed little consideration in the manuscript for how the quality of the published evidence might impact the review

      10/n As we pointed out in our systematic review and meta-analysis of COVID-19 IFR, this is an issue because higher-quality studies tend to show a lower seroprevalence and thus a higher IFR https://www.sciencedirect.com/science/article/pii/S1201971220321809 …pic.twitter.com/Jf2TJH3GVP

      11/n (Interestingly, Ioannidis cites our study but gets the numbers wrong, in what is distressingly something of a trend in the paper generally - we actually estimated 0.68% in the published paper which came out recently)pic.twitter.com/63z3Mw61uS

      Independent double-checking of data extractions once more shows its importance. This is why we teach people not to do SRs on their own.

      Yes! Never a good idea to take on such a mammoth effort by yourself, no matter how eminent a professor you may be

          Thanks ..My head hurts.. 😄 It boils down to ..looking at all the stats, the figure is probably around 5 but even that can’t be certain?
