Re: Evidence based medicine: a movement in crisis?

What I find amazing in face of all the rhetoric about "evidence-based medicine" is that the science on which it depends largely lacks actual replication or even the susceptibility to replication. If legally protected free "commercial speech" and "trade secret and intellectual property" laws prevent independent sources from gaining access to the raw data and code books used to analyze and report findings, how can any of the so-called "evidence" be deemed credible? Only one of 10 PLOS published authors who pledged as condition of publication to share their research data when asked to do so actually delivered on their promise: http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0007078. Evidence-based medicine will become a possibility when it begins to play by the rules of empirical science--beginning with its first principle of replicability.
