In the Original Investigation titled, “Comparison of Drugs Used for Adjuvant and Metastatic Therapy of Colon, Breast, and Non–Small Cell Lung Cancers,”1 published on April 10, 2020, in JAMA Network Open, the authors failed to describe and cite a previously published study2 that reported a conceptual model that informed the design of this study. The article has been corrected to add a description of and citation to this previous study to the Methods section and to add a note to the legend of Figure 1 that its presentation and format were based on a figure in the previous study.
