From your first link:
"This far into the pandemic, with double-blind, randomized, controlled clinical trials starting to be published and showing, each and every one of them so far, that hydroxychloroquine shows no benefit "
And as Dr. Risch says, these trials were on either hospitalized patients (when it's too late to be effective) or on patients too young to yield statistical differences in hospitalizations/death rates.
"If a drug strongly inhibits coronavirus replication, there’s no reason that it couldn’t be effective both in advanced disease and in early disease"
This is complete nonsense. It's like saying it doesn't matter if you treat cancer early or late if the treatment is effective. HCQ+ prevents the problems that arise later in the progression of the disease. This statement gives tons of credence to my argument that there is a widespread lack of logical thinking ability among medical professional types. The rest of the article contains terrible logic in making a few of the "rebuttals."
Your second link deals EXCLUSIVELY with the 42-patient study in France, which Dr. Risch has already said is not a valid study.
Here's the bottom line: Until you read the entirely of Dr. Risch's paper, anything you say in rebuttal is nonsense.
