:::::::While I think EMP is right to discuss this here...I don't see what criteria Doc is using to make what seem to be personal judgements on what are the "best "studies. "Best" is a matter for discussion not one editor's opinion. And there's that word "independent" again. Perhaps we can get down to a discussion that deals with defining this word per Wikipedia. I believe its being used here inappropriately then applied to make judgments on research.(  )
