Fig. 5From: The prognostic role of pre-treatment neutrophil to lymphocyte ratio and platelet to lymphocyte ratio in esophageal squamous cell carcinoma treated with concurrent chemoradiotherapyKaplan–Meier plots of PFS and OS according to NLR and PLR. A NLR ≥ 2.47 was an adverse prognostic factor for PFS (P < 0.001). B PLR ≥ 136 was an adverse prognostic factor for PFS (P < 0.001). C NLR ≥ 2.47 was an adverse prognostic factor for OS (P < 0.001). (D) PLR ≥ 136 was an adverse prognostic factor for OS (P < 0.001)Back to article page
