Not sure you're reading it right there - "I think this basically agrees with my analyses above - the trends really are in ivermectin’s favor, but once you eliminate all the questionable studies there are too few studies left to have enough statistical power to reach significance."

So I'll revise - studies have been done, but no conclusions about positive efficacy can be supported.

"I think the conventional wisdom - that the most extreme ivermectin supporters were mostly gullible rubes who were bamboozled by pseudoscience - was basically accurate."
