This recently-released paper has been "chewed on" at a number of places this week. Here's the funniest report I have seen so far:
So glad I had that lecture last week about how science works. Reminded me that I needed to do a post like this. People have been crying out for gold-standard randomized placebo-controlled double-blind clinical studies. This study is the aluminum standard, I guess.. It's not a randomized placebo-controlled double-blind study, and the sample size is too small for it to ever be included in one of those fancy evidence-based libraries that I don't have a card to.
I don't know how IT got through. The control group isn't really a control, even though that is what they called it. They are using it as more of a baseline standard. That double-blind thing is mainly nonsense. People usually know what they are eating. I think these folks figured out they were hungry.
Just sayin' this study isn't randomized. Can you point out the Where's Waldo?
