Prognostic value of the RDW-cv and NLR in stage II–III GC patients who received radical surgery. (A) Kaplan-Meier curves for the OS differed in the RDW-cvhigh group (n=50) and RDW-cvlow group (n=101) patients (P=0.051, log-rank test). (B) Kaplan-Meier curves for the OS differed in the NLRhigh group (n=71) and NLRlow group (n=80) patients (P=0.157, log-rank test). (C) The DFS differed in the RDW-cvhigh group (n=50) and RDW-cvlow (n=101) group (P=0.036, log-rank test). (D) The DFS differed in the NLRhigh group (n=71) and NLRlow (n=80) group (P=0.001, log-rank test). RDW-cv, red blood cell distribution width-variation coefficient; NLR, neutrophil to lymphocyte ratio; GC, gastric cancer; OS, overall survival; DFS, disease-free survival.
