I could go back and try to find the JAMA or New
England Journal I read stuff in for
you, online, but since the internet, I threw out the old stacks I possessed (as have most not prone to endless stacks)......there are far more recent studies on all these things anyway now. Try Pubmed for the basics, you have to subscribe to NEJ, JAMA, etc now.
Normally, I would pull up all KINDS of these several links for you as I have for most everyone, and spent hours helping individual ones......
