In this paper by Palmer and colleagues (BMJ 2019;364:l185, doi:10.1136/bmj.l185, published 7 February 2019), the international hip outcome tool iHOT-33 (iHOT) and EQ-5D Visual Analogue Scale (VAS) were presented on a 0-10, instead of a 0-100 scale. As such, the adjusted treatment effects for these secondary outcomes, presented in table 4, should read 20.4 (95% confidence interval 13.2 to 27.6) [not 2.0 (95% confidence interval 1.3 to 2.8)] for iHOT-33, and 7.5 (95% confidence interval 2.7 to 12.3) [not 0.7 (95% confidence interval 0.3 to 1.2)] for EQ-5D-VAS. The corresponding P values remain unchanged.
