Diagnostic implications of neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and systemic immune-inflammatory index for gastric carcinoma

Figure 1 Levels of neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and systemic immune-inflammatory index in the gastric carcinoma and precancerous gastric condition groups. A: Neutrophil-to-lymphocyte ratio levels in the two groups; B: Platelet-to-lymphocyte ratio levels in the two groups; C: Systemic immune-inflammatory index levels in the two groups. ^aP < 0.001 in the inter-group comparison. GC: Gastric carcinoma; NLR: Neutrophil-to-lymphocyte ratio; PLR: Platelet-to-lymphocyte ratio; SII: Systemic immune-inflammatory index.

Figure 2 Receiver operating characteristic analysis of the diagnostic implications of neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and systemic immune-inflammatory index for gastric carcinoma. A: The receiver operating characteristic (ROC) curve of neutrophil-to-lymphocyte ratio (NLR) in the diagnosis of gastric carcinoma (GC); B: The ROC curve of platelet-to-lymphocyte ratio (PLR) in the diagnosis of GC; C: The ROC curve of systemic immune-inflammatory index (SII) in the diagnosis of GC; D: The ROC curve of NLR + PLR + SII in the diagnosis of GC. NLR: Neutrophil-to-lymphocyte ratio; PLR: Platelet-to-lymphocyte ratio; SII: Systemic immune-inflammatory index.
