In the version of this article initially published, the author list (John H. Krystal and Robert L. McNeil Jr.) was incorrect. The correct author list is simply ‘John H. Krystal’. The correct ‘Competing interests’ statement is, accordingly, “The author declares no competing interests.” The errors have been corrected in the HTML and PDF versions of the article.
