Cumulative receiver operating characteristics for analyzing interaction between tissue visfatin and clinicopathologic factors in breast cancer progression

Table 4 Performance of scores from cumulative ROC analysis in predicting breast cancer progression.

Scores of dichotomized factors^a	Sensitivity (%)	Specificity (%)	Sensitivity + specificity (%)	Correctly classified (%)	LR+	LR−
1	100.00	14.29	114.29	31.43	1.17	0.00
2	100.00	45.24	145.24	56.19	1.83	0.00
3	95.24	65.48	160.72	71.43	2.76	0.07
4	76.19	85.71	161.90	83.81	5.33	0.28
5	42.86	94.05	136.91	83.81	7.20	0.61
6	19.05	97.62	116.67	81.90	8.00	0.83

LR+ Likelihood ratio for a positive test result, LR− Likelihood ratio for a negative test result
^aThe number of dichotomized factors was the cumulative effects of the various clinicopathologic factors from Table 3, including HT, tissue visfatin, LN metastasis, stage, age, and tumor size
