1 Screening mammography examinations: Mammography examinations indicated by the radiogist to be for screening with bilateral views done and no other mammogram within the past 9 months among women without breast implants or a prior breast cancer diagnosis.

2 Sensitivity = The percentage of cancers§ that had a positive interpretation&.

3 Specificity = The percentage of non-cancers~ that had a negative interpretation#.

4 PPV (Positive Predictive Value) = The percentage of examinations with a positive interpretation& that result in a tissue diagnosis of cancer§.

5 Recall = The percentage of examinations with a positive interpretation&.

§ Cancers = Examinations with a tissue diagnosis of ductal carcinoma in situ or invasive cancer within one year and before the next screening mammography examination.

~ Non-cancers = Examinations without a tissue diagnosis of cancer within one year or before the next screening examination, whichever occurs earlier.

& Positive interpretation = BI-RADS category 0, 3 with a recommendation for immediate follow-up, 4, or 5.

# Negative interpretation = BI-RADS category 1, 2, or 3 with no recommendation for immediate follow-up.
