In a 2 minute look at that article i can say immediately 2 or 3 things:
"A study out of China in 150 hospitalized patients conducted at 16 sites showed that hydroxychloroquine did not help patients clear the virus better than standard care."

Just HCQ? Did they added zinc + Azithromicyn ?
At what stage were the patients? Being Hospitalized, i imagine it wouldn't be initial stage... And it's exactly there where HCQ shine.

(...)"That study examined 81 hospitalized patients in Manaus, Brazil and was sponsored by the Brazilian state of Amazonas. "

Outch! Just that "study" deserves a whole video... It was criminal!
Do you know the dosage they used? It was more than double the fatal amount (of 6 grams) and people died... http://www.francesoir.fr/politique-monde/oxford-recovery-et-solidarity-overdosage-two-clinical-trials-acts-considered

For Covid, the protocol that is used is 400mg on first day, and then 200mg per day - that's nothing near the toxic dose or what they used in Manaus... It's a shame to even refer that study

Anyway, i can tell you that that article is "old" (April), pure BS, and most of it was already debunked.

Have a great day :)
