Typographical Error in Table 3

In the article titled, “Performance of Screening Ultrasonography as an Adjunct to Screening Mammography in Women Across the Spectrum of Breast Cancer Risk,”¹ a typographical error was present in Table 3 on initial publication. The row that previously read “Cancer detection rate per 1000 (95% CI)” was updated to read “Cancer rate per 1000 screens (95% CI).” This article was corrected online.
