Resumen de Error in Reported Data for Dense Breast Notifications

• In the Research Letter entitled “Content, Readability, and Understandability of Dense Breast Notifications by State” published in the April 26, 2016, issue of JAMA,1 there was an error in the reported data in the Table, which also affected the Figure and the text. In the Table, under the Mandate Language column, check marks needed to be added for Nevada and Oregon (Oregon only mandates language for women with extremely dense breasts); under the Increased Risk of Cancer column, check marks were added for New Jersey and Louisiana; under Supplemental Screening column, footnote “m” was removed from Oregon, the check mark and footnote “k” was removed from New Jersey, and check marks were added for California, Tennessee, Maryland, North Carolina, Pennsylvania, and Minnesota. In the Results section of the text, second sentence, first paragraph, "19, 83%" was changed to "21, 91%"; in the fourth sentence, "15 (65%)" was changed to "20 (87%)"; and in the fifth sentence, "15" was changed to "20."
