I think reference number 191 is not that number any more. I think the reference that Octopet referred to is the WHO one (at least it contains this list of "diseases, symptoms or conditions for which acupuncture has been proved through controlled trials to be an effective treatment"). However, this (peculiarly bold) WHO statement is less authoritative than the underlying medical literature (per WP:MEDRS), so I don't understand all this ruckus. "Clinical trials have so far produced little evidence for the efficacy of TCM therapies, such as acupuncture." still sounds very accurate to me.
