Incorrect Author Name and Affiliation

In the Letter to the Editor titled “Association of Tramadol vs Codeine Prescription Dispensation With Mortality and Other Adverse Outcomes,” published in the February 1, 2022, issue of JAMA,¹ an author name and the affiliation for a coauthor were incorrect. In the byline, “Shu Hsin Yi” should have read “Hsin-Yi Shu,” and in the author affiliations, “Yi” should have read “Shu.” The affiliation for Dr Wei, reported as “Chung Shan Medical University,” should have read “Chung Shan Medical University Hospital.” This article was corrected online.
