Final week, Tyler Cowen printed a hyperlink to a current examine of the usage of ivermectin in sufferers who had had Covid-19 for a median of 6 days. As is his wont, he doesn’t say a lot in regards to the examine (aside from a quizzical remark about Scott Alexander) however merely hyperlinks to it. Most of the commenters on that web site, although, appear very positive that ivermectin will not be useful for these within the early phases of Covid-19. After all, as with most feedback, it’s tough to inform what bases they’ve for his or her views.

Charley Hooper and I’ve written extensively about ivermectin (for instance, right here, right here, right here, and right here) and have identified how poor a number of the primary research and, specifically, the TOGETHER examine, are.

This newest examine seems to be no exception. Right here’s an in depth critique.

The factor Charley and I observed proper means in that critique is what the evaluators label as Essential downside #13: Very late therapy.

If you happen to go to this web page and scroll down just a little to the graph of efficacy versus therapy delay in days, you see that a lot of the remedies studied must be administered within the first 2 to 4 days. When was the therapy on this newest examine administered? The median time was 6 days.

Additionally, observe the Essential downside #33: Excessive battle of curiosity. “The ACTIV government committee was chaired by workers of J&J and NIH, and is now chaired by workers of Pfizer and NIH. Different members of the committee are from NIAID (Dr. Fauci), FDA, and Pfizer.”

If you wish to discover that ivermectin is ineffective, you’ll be able to absolutely accomplish that.
