Error in Byline

The Original Investigation titled “Single-Dose Psilocybin Treatment for Major Depressive Disorder: A Randomized Clinical Trial,”¹ published in the September 5, 2023, issue of JAMA, was corrected to fix an error in the 95% CI for the mean difference in Sheehan Disability Scale scores and to add an additional author to the byline. This article was corrected online.
