In Reply In their letter regarding our Viewpoint,1 Philpotts and Durand call attention to 3 studies. First, they take issue with the reference in our article to the study by Sharpe et al,2 an observational study that evaluated changes in recall among women undergoing breast cancer screening after the introduction of digital breast tomosynthesis. The study did not find a significantly lower recall rate with digital breast tomosynthesis among women 70 years and older compared with 2-dimensional mammography. Philpotts and Durand cite a critique of that study,3 but the critique expressed concern that the analysis had overestimated effectiveness of digital breast tomosynthesis, not underestimated it. In addition, the critique likely reflected a misunderstanding of the analysis rather than an actual error in the original publication.3
