Well, you're absolutely right. Something that seems promising in vitro is not always useful in vivo. A drug that works great on a cell culture may never even reach the cells in question when applied to a living body, which is basically a giant maze.
However, that's not what I meant. Look at those links I posted again. Many trials have failed to post any results at all, even over a year after their completion. Not positive, not negative. Nothing. No data. That's so frustrating to see.
A number of possibilities. Could be that they are still writing up the data, but since these trials you linked are generally very small numbers of patients (<100), it shouldn't take them long to analyze. Could be that they failed somewhere along the way with recruitment, or administrating the intervention, or maintaining the blindedness, etc. Could be that their results were negative and so they just gave up and didn't bother to write them up.However, that's not what I meant.

Isn't there anything that can be done in terms of surveillance and early treatment before they become critically hypoxic?
Vaccination.If you get as far as the hospital with COVID then you'll get all the treatments we have good evidence for which I outlined above - dexamethasone, remdesivir, tocilizumab, NIV - all with the aim to prevent intubation.
I have seen so many instances where people go over the topic of COVID-19 death certificates, hear that a PE, stroke, or myocardial infarction killed someone who was sick with COVID-19, and then angrily grumble something about how hospitals are inflating COVID-19 numbers by designating deaths from infarcts as COVID deaths.
Tell that to your fellow anti-vaxxers. They are the ones perpetuating this nonsense.I know they're trying to prevent a panic, but at this stage, more information is better. It has to be.
We give out plenty of information, barn door irrefutable information, and still some people deny it. People look at the death rates and falsely claim they are being inflated, as you just pointed out. People deny that hospitals are full, when we've literally taken over entire floors to turn them to expanded ICUs. People don't even think COVID is real, despite it being isolated hundreds of thousands of times and killing millions. Explaining the intricacies of COVID pneumonia or multi-organ failure isn't going to change the mind of these people. Indeed, as evidenced by this very thread, if you try to do so you get simply get insulted and told to go die. 
Lots and lots of people are very scared.
Absolutely. And feeding them provable lies about how our single greatest weapon in the fight against COVID is gene therapy or mind control or nanotech or any other nonsense is the root of a lot of that fear.
