Figure 1 Comparison of receiver operating characteristic curves with metastatic lymph node ratio, log odds of positive lymph nodes, and positive lymph nodes staging methods. A: Receiver operating characteristic (ROC) curves with no staging; B: ROC curves with staging. MLR: Metastatic lymph node ratio; LODDS: Log odds of positive lymph nodes; pN: Positive lymph nodes.
