A New Model for Predicting Nonsentinel Lymph Node Metastasis in Early-Stage Breast Cancer Using MMP15

Table 4

The ability of the new model to screen low-risk NSLN metastases with a cut-off of 50%, 60%, or 70%.

Cut-off point	Covered patients	Number of patients with NSLN metastasis	Specificity (%)	False-negative rate (%)	Negative predictive value (%)	Total coincidence rate (%)
≤50%	37	2	36.5	3.2	94.6	60.1
≤60%	49	4	46.9	6.5	91.8	65.2
≤70%	66	9	59.4	14.5	86.4	69.6
