I was reading through the research that shows the data. It is my understanding that NIH only allows randomized, controlled, double blind trials. I am aware of the biases within the pharmaceutical companies and what they choose to test, for example, they will not use bio identical progesterone in trials, only progestin is used because progesterone can not be patented. Meta analysis is only as good as the data, and data is only as good as the experimental setup and the parameters being tested.
