Explain to me what it is you are getting from this that is different than what the authors repeatedly conclude.
Absolutely nothing. What I conclude is exactly the same as what the authors conclude and is exactly the same as what you have posted here.
It is you who are disagreeing with the authors and dont know it. I have explained to you three times now exactly what your misunderstanding and you just ignore it and keep repeating yourself. Again this is not appropriate for a medical doctor.
I will explain to you again, in this study “the patients with COVID” are specifically explained to NOT be a random sampling of the population of people with COVID. It is not meant to be representative of the COVID population. It is specifically only people who have unusually bad cases and wind up hospitalized. Therefore it is only representative of hospitalized COVID infected people, it is NOT representative of COVID infected people in general.
