The 5 days of treatment for any patient. Pretty clear.
Do you see any dates of treatment? I didn’t. There can’t be too many because the disease has only been here for a few weeks. For him to have collected 500 patients or 350 or whatever he must have “formed his study group” very recently. He claimed people who were not terribly ill if they were all outpatients. His end point is “shed virus”. That may imply an outcome but it is damn far from proving anything. I have read this pathetic email 5 times now and each one was a waste of damn time.
As my professor of Pharmacology used to say, he could ladle carrot soup on a patient and write a damn paper. Funny, the first thing he told us is never prescribe a drug that has been on the market less than 2 years. Let other people discover the complications.
