"Lockdowns only reduced mortality by 0.2%" claims (unreviewed) meta study, and it is getting much press in @FoxNews and the like.

A #metastudy aggregate the entire body of evidence. This one is based on 18,590 studies.
So, 0.2% must be a credible estimate... Well. No so fast. 🧵 A meta study often begins with a large set of studies (18,590) then eliminates irrelevant studies, duplicates, etc.

This meta study ends up with 34 papers.

Thus 0.2% is based on 34 studies, right? Well, actually not. Image
