Ivermectin: Much More Than You Wanted To Know

I know I’m two months late here. Everyone’s already made up their mind and moved on to other things. But here’s my pitch: this is one of the most carefully-pored-over scientific issues of our time. Dozens of teams published studies saying ivermectin definitely worked.

The Summary

  • Ivermectin doesn’t reduce mortality in COVID a significant amount (let’s say d > 0.3) in the absence of comorbid parasites: 85-90% confidence
  • Parasitic worms are a significant confounder in some ivermectin studies, such that they made them get a positive result even when honest and methodologically sound: 50% confidence
  • Fraud and data processing errors are of similar magnitude to p-hacking and methodological problems in explaining bad studies (95% confidence interval for fraud: between >1% and 5% as important as methodological problems; 95% confidence interval for data processing errors: between 5% and 100% as important)
  • Probably “Trust Science” is not the right way to reach proponents of pseudoscientific medicine: ???% confidence
