Incorrect Sentence in the Abstract

In the Original Investigation entitled “Effectiveness of Digital Breast Tomosynthesis Compared With Digital Mammography: Outcomes Analysis From 3 Years of Breast Cancer Screening” published online February 18, 2106, and to be published in the June print issue of JAMA Oncology,¹ an error occurred in the Results portion of the Abstract. The last sentence, which read, “Interval cancer rates, determined using available follow-up data, decreased from 0.7 per 100 women screened with the use of DM to 0.5 per 1000 screened with the use of DBT1.” should be replaced with “Interval cancer rates, determined using available follow-up data, decreased from 0.7 per 1000 women screened with the use of DM to 0.5 per 1000 screened with the use of DBT1.” This article was corrected online and will be correct in the print issue.
