Yes. The control should be those who would normally be proscribed HCQ but were not...what was their mortality rate.?
Without this then the study is simply reporting the results rather than efficacy.
So, let me get this straight. The mortality rate of patients hospitalized for COVID is somewhere around 35-40% across the nation. But the VA rate is 20% overall and 25% for HCQ patients. I would call that a success.
