From: Clinical implications of metastatic lymph node ratio in gastric cancer
Survival curve and comparison of cumulative survival rates after surgery according to the metastatic lymph node ratio, calculated by dividing the total number of lymph nodes that have been removed and examined by the number of metastatic lymph nodes (0%, < 40%, 40–79, and ≥ 80%). There were significant differences among the groups (P < 0.00; Kaplan-Meier and log-rank test).
