      21/n If you dig through the supplementaries, what you find is that for "all reported symptoms" there was a large but statistically insignificant difference, represented in this graph of marginal predicted probabilities from a logistic model. It is mostly driven by an/hyposmiapic.twitter.com/h64IdG4LJF

      22/n If you eyeball "any symptoms", you get the results that ivmmeta included in their analysis But that's TOTALLY ARBITRARY. Why not choose cough (where there's no difference) or fever (where IVM did WORSE)

      23/n Also, hilariously, this study used the last observation carried forward method to account for missing data in symptom reporting. You can actually see this in the supplementaries - it's possible the entire result comes from a few people not filling out their diaries properlypic.twitter.com/rA7PO4o4hd

      24/n None of this should matter, because the trial found NO BENEFIT FOR IVERMECTIN, but this has been reported and included into ivmmeta dot com as a hugely beneficial resultpic.twitter.com/mjGBDnpVW5

      25/n This explains the bias I noted above - it's not publication bias, it's that the authors appear to have generally chosen whichever result makes ivermectin look better to include in their model Not really scientific, that!

      26/n But the fun doesn't stop there. The inclusion criteria for this website is any study published on ivermectin, which has led to what I can only call total junk science being lumped in with decent studies

      27/n Here's a study with impossible percentages in table 1 that used a comparator of 12 completely random patients as their control. They don't even say if these 12 people had COVID-19 Included in ivmmeta, no questions askedpic.twitter.com/3AlGdGcPnW

      Health Nerd is correct that the percentages cannot be the result of the numbers listed. But he's there is a lot of context that should be understood, and I find this in fully half the papers I read, regardless of other qualities. It happens when...

      Replying to @EduEngineer @GidMK

      It happens most often when the staff is small and not well enough trained in number sense to catch where they've changed the underlying patient pool after computing the percentages. Once in a blue moon, such an error is entirely critical to the outcome. Mostly, it's messy.

      Typically, in nations outside the Western pharmasphere, this happens because it's mostly doctors working without a professional statistician, and that does not mean the labor itself was not quality.

      Lol, that's absolute nonsense. Some of the best research during COVID-19 has come from outside the "Western pharmasphere", most of it includes statisticians and does not have impossible values in the studies
