*
aOR = odds ratio adjusted for registry site, race/ethnicity, family history of breast cancer, breast density, history of breast procedure, current hormone therapy use, time since previous mammogram, and examination year.
**
PPV1 = Positive predictive value
***
CDR = cancer detection rate per 1000 examinations
