Table 4.

The actual number of positive cases correctly identified (sensitivity levels) at different specificity levels when applying the ANN to classify the dataset with 100 positive and 100 negative cases

Specificity	95%	90%	85%	80%
Sensitivity on all 100 positive cases	34 (34.0%)	42 (42.0%)	44 (44.0%)	51 (51.0%)
Sensitivity on 39 cancer cases	14 (35.9%)	17 (43.6%)	18 (46.2%)	20 (51.3%)
Sensitivity on 21 interval cancer cases	12 (57.1%)	13 (61.9%)	13 (61.9%)	15 (71.4%)
Sensitivity on 8 high-risk cases (surgery excision)	2 (25.0%)	4 (50.0%)	4 (50.0%)	5 (62.5%)
Sensitivity on 32 recalled negative cases	6 (18.8%)	8 (25.0%)	9 (28.1%)	11 (34.4%)
