Providence Health Services quoted your article at http://www.providence.org...
They seemed to miss the statement in the Conclusions that this study did not speak to causation, but ran their article as if it did prove causation. I find this trend disturbing, and would like to see more accurate use of scientific studies used in healthcare teaching, as well as in general media stories. It starts with someone speaking up. Be the change you want to see.
