Preoperative immunonutrition status predicts survival after colorectal cancer resection: Nomogram based on modified systemic inflammation score

Figure 1 Receiver operating characteristic curves of serum albumin and neutrophil-to-lymphocyte ratio in the training cohort. Receiver operating characteristic (ROC) analysis was performed to evaluate the discriminatory ability of serum albumin (red curve) and neutrophil-to-lymphocyte ratio (NLR) (black curve) for the study endpoint. The area under the curve (AUC) was 0.785 for albumin and 0.683 for NLR. The optimal cut-off values determined by ROC analysis were 38950 for albumin (sensitivity = 0.781, specificity = 0.718) and 2.958 for NLR (sensitivity = 0.874, specificity = 0.474). The difference between the AUCs was statistically significant (P = 0.032883). ROC: Receiver operating characteristic; AUC: Area under the curve; NLR: Neutrophil-to-lymphocyte ratio.
