The area under the receiver operating characteristics curve(AUC) characterizing benign and malignant lesion discrimination was 0.884 (95%CI: 0.836~0.932,
P<0.001) for PI(see Fig.1).
The sensitivity of PI was 82.4%,
which was significantly higher than that of physical examination (48%,
P=0.000) but lower than that of either mammography (93.6%,
P=0.003) or ultrasound (95.5%,
P=0.000).
The specificity of PI (80.0%) was significantly better than that of mammography (55.7%,
P=0.002) and ultrasound (62.3%,
P=0.023),
and similar to that of physical examination (91.4%,
P=0.096) (see Table 1 and Table 2).
For patients with different breast composition on mammography,
PI had similar sensitivity (87.3% for <50% glandular,77.4% for >50% glandular,P=0.166) and specificity ( 85.7% for <50% glandular,79.4% for >50% glandular,P=1.000).
