100%Seems like some of you are confusing correlation with causation. Simply because someone receives a treatment and ends up dead does not mean that treatment is adding to the risk of death. What this tells us is that we need to know more about the non-survivors - e.g. did they receive a treatment too late? Are there other unobserved variables (yes, most likely) that influence the outcomes? No researcher with self-respect would derive strong conclusions from univariate analyses. The study suffers from endogeneity issues and is only a teaser - not a study we should base much of anything on.
Yes, and it’s the sickest people of all that need oxygen and other interventions to this extent. Without it they may quite possibly either die or live in a persistent vegetative state and have anoxic injury. Either way it doesn’t look good but at least there are people out there genuinely trying to help. If people don’t want to run the risk of getting these treatments they should definitely not go to the hospital because that’s the best we have to offer at this time.All sorts of oxygen therapy were predictive for bad outcome. Data taken from table 2.
