"Although the content of the British Chiropractic Association's list is important, its omissions are perhaps even more so. At least three relevant randomised controlled trials and two systematic reviews are missing from it. Arguably, these are the most rigorous papers in this area, but they fail to show that chiropractic is effective. The omissions are all the more curious as the association apparently knew of these articles." Edzard Ernst, British Medical Journal (9th July 2009)
