Someone at my church brought this up a few weeks ago and this website is a perfect example of some of the shady stuff being used to prop up ivermectin. First this meta-analysis lumps studies that have entirely different study design (RCT, observational) and primary outcomes (clearance of viral cultures, symptom resolution, etc) which is a something a big red flag. In addition it picks and choses which results to use. For example a study from Ahmed that is listed on that site found no statistical benefit using ivermectin for symptoms (fever, cough, SOB, etc) and actually slightly longer hospitalization for those taking ivermectin and doxycycline compared to no treatment though not statistically significant. However it reported 100% of patients were afebrile in the ivermectin group by 7 days compared to 3 who still had a fever in the placebo group. They ignore other symptoms such as cough for which more people in the ivermectin group had after 7 days than placebo but decide to use fever as a marker of symptom resolution. You can see for yourself by reading the study and looking at what ivmmeta.com uses for analysis (though this study has a lot of problems with its data reporting and should be excluded from any analysis).

They do this for many many other studies which is maddening. In addition they still include trials that have been retracted and report meta-analyses that include other studies that have been retracted.
I bet the people who run this site could make Coach Pruitt or Dooley seem like world class coaches by their statistical chicanery.
