a
Breast density was based on fourth edition Breast Imaging Reporting and Data System (BI-RADS)20 categories (1, almost entirely fat; 2, scattered fibroglandular densities; 3, heterogeneously dense; and 4, extremely dense) collapsed into nondense (BI-RADS 1 or 2) and dense (BI-RADS 3 or 4).
b
The overall recall rate for digital mammography was 11.2% and for digital breast tomosynthesis was 8.7%.
