Please tell me who are the authors of the website you mentioned and tell me what is the methodology they used for selecting the studies and rating them.
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.
