Table 4 Comparison of the performance of the AJCC-N, LNR, LODDs, and the rN staging systems in predicting prognosis of gastric cancer

From: Retrieved lymph nodes from different anatomic groups in gastric cancer: a proposed optimal number, comparison with other nodal classification strategies and its impact on prognosis
