Why questionable? The only way to put a stop on the HCQ debate is doing proper clinical trials (not retrospective, not observational, proper double-blind randomized drug vs placebo trials). All the preprints I've come across are wasted opportunities because they lack in one or more areas (too late during treatment course; insufficient number of patients; no proper controls...). The one by U of Minnesota[1], which at least from the sources I read is getting very little publicity, is struggling to get the remaining 150 patients to get enough power to give an answer. This is where we should bet our "money" (figuratively speaking) on. [1] https://covidpep.umn.edu/ https://covidpep.umn.edu/
