No drug, procedure, or regimen ever SAVED anyone’s life. The best they can do is extend one’s life.
This is a bogus study anyway. It compares the number of deaths to an “estimated” number of deaths that would have occurred without the procedure. Everyone should read the book Worried Sick by Nortin Hadler, MD. We are being conned by all these so-called preventive tests and procedures.
If nothing else, look up what relative risk is, because that is how most of these studies are reported.
