Let’s talk about the zinc. This supplement has gone viral together with #hydroxychloroquine and #azithromycin hype, and has been promoted without scientific evidence.
thread🔻
Most Zinc supporter refer to this article published on PLoS Pathogen in 2010, which described an in vitro inhibitory effect of Zn against SARS-CoV. Author also suggests the RdRp-dependent potential mechanism. Can this be translated to SARS-CoV-2? Let’s dive in. Image

a "highly-(self)-cited" preprint from #raoult suggesting in vitro synergy of #hydrodroxychloroquine + #azithromycin against SARS-CoV-2 got accepted by Microbial Pathogenesis.

sciencedirect.com/science/articl…

a 18-day "serious" peer review happened

Let's see what we have(troll face)🔻 This paper is more like a beautiful mathematic proof - concise but "brilliant" -

"we proved that synergy is true. period"

Abstract: 93 words
Result: 143 words

🤣🤣🤣

Having seen so many double standards on #remdesivir and #hydroxychloroquine result, I decide to start a thread to share how I read a scientific paper.

While I only expect 1% people who finally adopt the protocol, I do hope scientists and famous writers have a try.

thread🔻 (1/) Links:
Remdesivir (NEJM)

Hydroxychloroquine + azithromycin (preprint)

(1/) An update of analysis of Dr. Raoult’s #hydroxychloroquine #azithromycin trial on 1061 patients.
mediterranee-infection.com/pre-prints-ihu/
(warning: it’ more like conspiracy theory) (2/) Actually the preprints have two versions.

“Version 2”

Final version

There're minor changes in the final version compared to v2. Most are Ct values and HCQ serum concentrations. Other baseline characteristics are the same.

Once again, data is broken, and I smelled their anxiety several days ago.


Threads🔻 (2/n) I closely monitor IHU’s COVID-19 website since the birth on 3/26.

mediterranee-infection.com/covid-19/

This website reports the number of COVID positives & death in APHM/IHU, and num of positives & death with >3d treatment. Some major discrepancies have been found.
