This doctor—who is an endocrinologist, not an infectious disease doc—has a history of publishing highly questionable “research.”
I read the study. It was not a randomized controlled trial; participants were choosing whether to take ivermectin or not. Since the participants were self-selected and the study was not randomized, it is impossible to say that differences in mortality were due to routine use of ivermectin.
The participants who took ivermectin also were more likely to have preexisting conditions, such as diabetes, which are known to increase fatality from Covid. Thus, they were more likely to be worried about dying from Covid. So they were more likely to volunteer to take the ivermectin and also to minimize their chances of being exposed to Covid.
What the study showed was not that ivermectin has an effect on Covid survival (in randomized studies, it does not), but that people who are more worried about Covid are more likely to take measures to avoid it.
Beware of medical misinformation. It was used against Trump (who no longer is president, largely because he was blamed for the misinformation) and it is being used against conservatives. The left would love for enough of us to die from Covid that they no longer have to cheat to win elections. Personally, I have no intention of helping the left.
Prevention is *always* better than waiting until you catch the disease and hoping something will cure you.
This won't matter. When you've drank the kool-aid for a particular issue, study protocol is just a minor nuisance that gets in the way of the results you want that study to prove.
