New embarrassingly bad study of ivermectin is a textbook example of “confounding by indication”
In short a retroactive database review found that people w/ COVID did worse if given remdesivir (only given to sick inpatients) than ivermectin (only given to well outpatients)🤔

There are many problems with this “study”.
First it’s generous to even call it a “study.” It’s an *abstract* of a retrospective database review. The whole “article” is less than a page (see below).
It wasn’t pre-registered.

The methods are weird.
They found 1.7 million people w/ COVID. Out of this group they identified 1,072 who received ivermectin (not exactly widely used) & 40k who received remdesivir
The groups were very dissimilar: IVM was 10 yrs younger. They don’t report any comorbidities
