      Today's paper that I'm checking is not ivermectin, another treatment for COVID-19, and thus far every single percentage I've looked at in every table is impossible Cited 18 times so far

      It looks like the authors have mislabeled table 1, but the other tables I can't even explain. These percentages, for example, aren't possible for any values between 40-45 as far as I can tellpic.twitter.com/qbsP3iUHM0

          The whole thing is just...very odd. The p-values are also bizarre - I get a chi-squared p-value of 0.0005, not 0.036, for the last line

          Percentages are a very easy check for quality - people have to be integers (can't have half a person), and so x/n = y% should always have a possible integer value for x given rounding

          Worth noting that lots of papers have one or two impossible values - often there is a person missing from one line in a table, that throws off the percentages. It's not ideal, but it's a very simple mistake It becomes worrying when this mistake is repeated a lot

          Table 1 is definitely swapped, at least. If we recalculate the % considering 44 to the treated arm and 43 people in the placebo data seems to match the %. This is a veeeeeeeery criticized paper here in Brazil and is also considered the new silver bullet for the gov. supporters

          Yeah. Swapping the N=43 vs 44 would fix some of it. I notice that 26% more had recovered by day 1, and the difference in recovery % is lower every day after that. Seems a bit odd to me.

          Yep, they've crossed over the n=43 and 44 numerous times in the paper quite clearly, but there are plenty of percentages that are impossible even with 43 or 44 so it's all very confusing

          They say in the text that they only tested 2/3 of the participants of the study, because of a low budget. Maybe that’s why the percentages are off.
