So I have a Q for the people that really understan

So I have a Q for the people that really understand the approval process. Am I to understand that it's just about numbers especially percentages as a comparison to the placebo arm, or is it more about where patients are in their severe or critical stage of the disease compared to the placebo arm? Also, what other factors, if any, are weighed heavily in the final decision? I do understand that deaths, as unappealing and sad that it has to be that way, are critical numbers towards the final approval. It almost seems like 2 trials in one. Can we be stronger in critical verses severe or vice versa or is it an all in one or nothing situation? With everything that I have learned I believe we are the best case scenario from Preventative to Mild to S/C but that's based on my d/d and some hopefulness. Please don't get me wrong, I understand competition, with guessing the deaths and I can tell most of these are scientific guesses. I also look at the statistics that some share here and to be honest I'm lost in those numbers, obviously not my forte! So if there's a way of explaining the whole process in layman's terms just so I can get a better understanding of the process as a whole versus bits and pieces. Thanks!
