In this paper by Helfer and colleagues (BMJ 2021;375:n2202, doi:10.1136/bmj.n2202, published 14 October 2021), a data supplement including all judgments made during the study was inadvertently overlooked and not published. This has since been rectified, and the article and PDF will be updated in due course.
