¹ Screening mammography examinations: Mammography examinations indicated by the radiogist to be for screening with bilateral views done and no other mammogram within the last 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.
