a survey of the literature? what survey? the data is not reachable via any public web site. u have to request it, and u have to have some level of medical credential to get it and understand it.
can i ask what your level expertise is to even comment on the subject? u strike me as the classic cut and paste cyber-debunk wannabie cliche. all generalities. nothing original. poorly articulated. and nothing offered with any depth of research.
