For the prediction of micro- and macrometastases, the nomogram showed poorer discrimination, with an AUC of 0.67, and was less well calibrated (average error =10.9%).
For the prediction of macrometastases, the nomogram showed good discrimination, with an area under the receiver operating characteristic curve (AUC) of 0.76, and was well calibrated (average error =2.1%).
For the prediction of metastases detected by conventional histopathology, the nomogram showed good discrimination with an AUC of 0.76 (95% CI 0.71 0.81) and was well calibrated (average error=2.1%, maximal error=10.5%), with no statistical difference between predicted probabilities and observed proportions (P-value of the U index=0.56).
Considering LN metastasis detected by conventional histologic analysis and ultrastaging, the nomogram showed poorer discrimination, with an AUC of 0.67 (95% CI 0.63 0.72), and was less well calibrated (average error=10.9%, maximal error=15.9%) with a statistical difference between predictions and observations (P-value of the U index<0.0001).
