Does acupuncture relieve pain?

Owing to an administrative error, Adrian White and Mike Cummings, the authors of this editorial (BMJ 2009;338:a2760; doi:10.1136/bmj.a2760), cited data from a previous version of the linked research paper. The standard mean difference between placebo acupuncture and conventional care was –0.42 (95% confidence interval –0.60 to –0.23), corresponding to a reduction of 10 mm (not 9 mm, as was stated) on a100 mm visual analogue scale. The difference between needling classic points and control points was –0.17 (–0.26 to –0.08), and the overall effect size of acupuncture in relation to usual care was 14 mm (not 12 mm) on a visual analogue scale.
