In the Original Investigation titled “Assessing the Potential for Patient-led Surveillance After Treatment of Localized Melanoma (MEL-SELF): A Pilot Randomized Clinical Trial,”1 published online on November 24, 2021, in JAMA Dermatology, there were 2 minor errors in Table 1. The number of participants with 1 melanoma was adjusted from a total of 77 to 76, and for 3 melanomas, from 10 to 11. The respective percentages were adjusted as well. These changes did not affect the results of the data analysis. This article was corrected online.
