can you show me any randomized multi center clinical trials showing any difference? No, no one is going to do that the money and political will just is not there and easily 99% of best practice lacks this gold standard.
If there were significant differences in outcomes they almost certainly have manifested themselves in some observable form by now.
The real fact of the matter is that as far as I can tell you are a bright individual who has no real experience in which to base any of your decisions. I would be a bit more impressed if you actually PRACTICED in any meaningful way, in the meantime you are at best a really funny Monday morning QB.
To use the canard "you don't know what you don't know" and you don't know a thing about being a clinician.
