Dozens? There is Zev Zelenko, Steven Smith, a California doctor at an urgent care, Didier Raoult in France, and only the last has written up his results as opposed to talking about them in interviews.
Studies, at least retrospective. Patient data, age, sex, weight, smoker, prior conditions, meds, disease course, when treatment started. Were patients tested.
