Addition of Group Name in Byline and Nonauthor Collaborators Supplement

In the Original Investigation titled “Manchester Procedure vs Sacrospinous Hysteropexy for Treatment of Uterine Descent: A Randomized Clinical Trial,”¹ published in the August 15, 2023, issue of JAMA, the study group byline and Nonauthor Collaborator supplement were inadvertently omitted. The byline has been corrected to include “for the SAM Study Group” and a new online supplement with a list of the SAM Study Group members has been added. This article was corrected online.
