It is very nice to see results with such a large statistics (not easy to reach in medical sciences). So to sum up in one line, we should look elsewhere to fight the virus, right? And people taking their drugs can safely continue doing so, can't they?
Negative results are also great. This is how we progress (and it is good to have them published as well to avoid other losing their time).
Yes, at the beginning of the epidemic, sartans and ace inhibitors had been accused of facilitating the progression of the disease, being drugs that increase the expression of the enzyme ACE2.
The intent of this research is to attest that there is no direct correlation between the two factors and that patients must continue their therapies regularly.
As for the large amount of data available, Lombardy, unfortunately, has been very affected and is therefore providing many useful indications (in almost all the posts that I am proposing in last weeks, hospitals and universities of this region are involved).
Thanks a lot for the clarifications!
