Abstract
How to design high quality acupuncture trials-a consensus informed by evidenceIn box 5 of this article by Yu-Qing Zhang et al (BMJ 2022; 376:e067476; doi:) the study's method of analysis was incorrectly described as repeated-measure analysis of variance.The online version has been corrected to say that the study used the Expectation for Relief Scale to measure patients' expectations at baseline and analysed the effect of expectations as a continuous variable using ANCOVA.In addition, a sentence in the section "Consideration 4: who should perform the intervention?"that referred to the effect of practitioner training and experience on pain has been removed because of changes to the supporting reference.
