Fig. 1 Receiver operating characteristic (ROC) curve analysis comparing predicted probabilities of lymph node involvement by the old three-variable Memorial Sloan-Kettering Cancer Center (MSKCC) nomogram (MSKCC1; AUC MSKCC1=0.822 [95% confidence interval (CI), 0.757–0.887], p<0.001); the old four-variable MSKCC nomogram (MSKCC2; AUC MSKCC2=0.830 [95% CI, 0.768–0.893], p<0.001); the new MSKCC nomogram (MSKCC3; AUCMSKCC3=0.747 [95% CI, 0.677–0.818], p<0.001); Briganti's nomogram plus total lymph nodes (BR1; AUCBR1=0.831 [95% CI, 0.767–0.895], p<0.001); Briganti's nomogram plus number of positive cores (BR2; AUCBR2=0.832 [95% CI, 0.771–0.893], p<0.001); and Briganti's nomogram plus percentage of positive cores (BR3; AUCBR3=0.840 [95% CI, 0.780–0.900], p<0.001).
