Correction to: Nature Reviews Rheumatology https://doi.org/10.1038/s41584-020-00565-z, published online 6 January 2021.

In the version of this article initially published, the affiliation for Maurizio Cutolo was incorrectly given as “Department of Rheumatology and Clinical Immunology, Charité University Medicine Berlin, Berlin, Germany” instead of “Research Laboratory and Academic Division of Clinical Rheumatology, Department of Internal Medicine, IRCCS Polyclinic Hospital San Martino, University of Genoa, Genoa, Italy.” The change has been made to the HTML and PDF versions of the article.
