to suggest the benefits may not be any more effective than their other courses of treatment.

Of course he omitted this part that doesn't exactly discredit the other studies (nor give credence to the absurd claim in the OP's article):

"Hydroxychloroquine, particularly when given with the antibiotic azithromycin, has received widespread attention following a controversial, small study of about 40 patients hospitalized with Covid-19 in France. In that study, the drug appeared to help clear the virus from the bodies of 26 patients who were given the medication, based on samples taken from nasal swabs. Experts have criticized the design of the study, calling it interesting but far from definitive."

And he completely overstated the fear mongering about liver damage (OK, lied, or intentionally misstated):

"Four patients given the medicine developed diarrhea and signs of potential liver damage, compared with three getting conventional treatment."

So four vs three, with signs of potential liver damage. Sure sounds like "In fact, more of the treated patients showed liver damage than in the control group." to me! I truly cannot fathom why people feel the need to lie about the possible benefit of trying and testing this drug more, and destroy their own credibility, simply because Trump may ultimately benefit. It's quite disgusting.
