the FDA reviews the results for approval or denial. The 'Pro-HCQ' cadre never did prove its effectiveness in the manner they prescribed....but Pfizer did...dramatically...with Paxlovid.
As for the Lancet, they showed professionalism in publicly retracting a faulty study...it would be nice if you'd acknowledge that HCQ+ has never been proven effective as a treatment for SARS-CoV-2.
