§ PPV1 = The percentage of examinations with an abnormal initial interpretation that result in a tissue diagnosis of cancer within 1 year.
|| PPV2 = The percentage of examinations with an abnormal final interpretation** that result in a tissue diagnosis of cancer within 1 year.
# PPV3 = the percentage of examinations with an abnormal final interpretation**, where it is known that a biopsy was performed as a result of the abnormal diagnostic examination, that result in a tissue diagnosis of cancer within 1 year.
