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.
