* Data available at Breast Cancer Surveillance Consortium (BCSC) website using screening examinations from 1996–2005.[32]
† Months since previous mammography.[26]
‡ Prevalence and incidence rates are taken from Table 1.
§ No previous mammography or first mammography.[26]
|| Published performance data for 40–49 and 50–59 age groups.[25]
¶ Recall for diagnostic imaging occurs within 90 days after the initial screening exam.
** Positive predictive value of a screening mammogram, which arithmetically equals the cancer detection rate/recall rate.[26]
