Why would anyone study correlation? Correlation is not the same thing
as causation.

I know that perfectly well and that's why I ask the way I do. To show
correlation is a trivial thing. To show causation virtually impossible
or requires standpoints which will be questioned by others and will
have very limited scopes.
I hate health care secrecy. If these data were available for free on
the Internet I would have done the investigation myself.
