The Original Investigation entitled “Effect of a Workplace Wellness Program on Employee Health and Economic Outcomes: A Randomized Clinical Trial,” published in the April 16, 2019, issue of JAMA, had errors in the Abstract, Figure, and the Additional Contributions section. In the Abstract, the number of employees at 140 randomly selected control worksites should have been 28 937. In the Figure, the title should have been Flow of Participants in the Trial of a Workplace Wellness Program on Employee Health and Economic Outcomes. In addition, data were reversed in 2 boxes in the flow diagram and should have shown that for the 20 intervention worksites, 1080 employees responded to the Personal Health Assessment (survey), 1066 participated in the clinical biometrics, and 1005 were insured by Cigna, and for the 20 primary control worksites, 1020 employees responded to the Personal Health Assessment (survey), 1006 participated in the clinical biometrics, and 986 were insured by Cigna. The Additional Contributions section should have shown a thank you to Sherri Rose, PhD, Harvard Medical School, for her statistical guidance on randomization, without financial compensation, and to Josephine Fisher, BA, an employee of the Harvard T.H. Chan School of Public Health for research assistance. This article has been corrected online.
