the control group does not have to be non treated patients although there are some that would refuse treatment or not qualify for some other reason. the control groups could be different treatment or doses. Ultimately randomized studies are important for bandwagon is not always correct even when rolling along at high speed. Look up a drug called xigris for a recent example. That one was going to end sepsis deaths. Turned out we were killing people faster with if.
Freegards Mom MD!
My best friend's uncle is probably going to die with COVID-19 today. The one I told you about that would not keep his cpap clean. His wife has it too but not as bad yet. She will survive prolly but Chris was the only one able to care for her (dementia).
As to HCQ/Zpac/Zn, we are going to get the studies. It just takes time. Sad that people have to die but it was always this way. "We are in God's hands!"
