The Original Investigation titled “Risankizumab for Ulcerative Colitis: Two Randomized Clinical Trials,” published on July 22, 2024, has been updated to fix the affiliation for Nobuo Aoyama and add the names of investigators (Federico Arguelles Arias, Toshiyuki Endo, Jill Gaidos, Jee Hyun Kim, Albert Pirmagomedov, and Nikolaos Viazis) missing from the original version of Supplement 3. This article was corrected online.
