how did you read this article and somehow come to the conclusion that ivermectin doesn't work for covid-19?
Notably though, at no point does the author even suggest it doesn't work - just that the statistical significance isn't high
In medical trials, statistical significance is the milestone to reach before broadly claiming something 'works'. Dozens of other treatments were put through trials. Some had promising initial results. Most didn't work.
You've claimed it doesn't work - nothing says that. Nothing even suggests that.
Edit: I see you might have confused me for a parent post by lalaland1125 who did claim this.
