We all know about the hierarchy of evidence, with meta-analyses of randomized trials at the top and expert opinion at the bottom. Use of certain drugs and operations can be supported by evidence according to this scale, but what is the evidence for stopping a major bleeding? Or operating on a hip fracture? Crossing the undefined border between untested hypotheses and self-evident, we can trust nothing but our judgment.
The session “What’s evidence” will address some important questions: Can we really trust randomized trials? Are prosthesis registry studies overinterpreted? And how do we deal with the placebo effect of surgery?
The speakers are all famous and controversial. David Healy is author of bestselling “Pharmageddon”, where he criticizes the drug industry, and analyses how randomized trials can be used to mislead. Jonas Ranstam is statistical reviewer for The Lancet and Acta Orthop, and has critically debated the interpretation of data from quality registries. Teppo Järvinen is involved in ongoing studies using sham surgery. He was senior author of the recent New England Journal article showing lack of benefit of meniscus surgery.
Chair of the session: Prof. Per Aspenberg (Sweden)
