What most interests me about this paper is why the New England Journal of Medicine accepted it for publication. NEJM is world's top medical journal and publishes only three or four papers of original research each week, so they must think this is pretty important and relevant to a general readership. I've got nothing against the paper itself - it's a randomised controlled trial which seems to have been well run - but the outcome is short term gain in a physical function score. I'd have expected more from the NEJM, so why were they so impressed?
I've just noticed that this post marks a small milestone - my 500th entry on this blog! but alas I can't think of anything portentous to say. But it must mean that I have 20 weeks to my 10th anniversary so will do better on that occasion.
