This is a collection of links with arbitrary ratings from anonymous authors. A propaganda piece.
Here is a real meta-analysis..

Some smart French guy debunked this site https://threadreaderapp.com/thread/1284493669895041024.html And c19trials, another disinformation piece from the same authors.. https://threadreaderapp.com/thread/1291126570392924160.html
I think given that Doctors such as Simone Gold are being fired simply for stating that there's scientific evidence that HCQ can treat Covid-19 it's somewhat expected that sites such as this will be done anonymously.
Only a fool or someone just looking for confirmation would take an anonymous sham of meta-analysis seriously.
