Not on that particular retracted document. It was specifically pulled because the research group would not provide data.
Hydroxychloroquine is an antiinflammatory used for Arthritis, Lupus and a few other inflammatory diseases. The same with ivermectin is has specifically targeted applications (this may have more merit but again, needs valid, verifiable research - not meta-analysis.)
The site that you are pulling all your inspiration and analysis from only confounds the issue of misinformation.
They are hiding behind anonymity which should not be the case. "We are PhD researchers, scientists, people who hope to make a contribution" - Arent we all. To be taken seriously they should list their qualifications for their analysts, PhD's, and any affiliations.
I've read a few... peer-reviewed? There's a lot of confounding verbiage in a lot of the ones that I read that would not make it through peer-review on RCT's, which many claim to be but are not. So many of the references on this site are cherry-picked retrospective observational papers.
They are the The FLCCC Physicians.
