I signed today, and added the following comment:

In my university days, had I presented a conclusion based on such shoddy reasoning I would not only have received a failing mark but would also have been subject to a caustic commentary concerning my inability to use logic and reason. Over the years, when examining studies on Medline, I have been distressed to see many studies - providing recommendations on the health of millions of people - demonstrating the same lack of basic logic and reason in support of the conclusions. Taxpayers in both the US and Canada are not well served by such rubbish - certainly, I am not amused by the waste of my hard-earned money on slip-shod pseudo-science.
