Fig. 1. Hematologic parameters (including LMR, NLR, and PLR) and prognosis. Kaplan-Meier estimates of disease-free survival in the 914 cases of the Y-group (patients aged < 45 years) (A), the 932 cases of the O-group (patients aged ≥ 45 years) (B) classified based on the cutoff values of each parameter (high group vs. low group). LMR, lymphocyte-to-monocyte ratio; NLR, neutrophil-to-lymphocyte ratio; PLR, platelet-to-lymphocyte ratio.
