Figure 1From: Preoperative neutrophil/lymphocyte ratio predicts overall survival but does not predict recurrence or cancer-specific survival after curative resection of node-positive colorectal cancer ROC curve for the NLR as a predictor of death due to any cause. The optimum threshold of 2.8 is indicated by A, at which point the positive predictive value was 56% (95% CI 47%-64%). B indicates a threshold of 3.8, at which the positive predictive value was 63% (CI 52%-74%). C indicates a threshold at 2.5%, at which point the positive predictive value was 52% (CI 45%-60%).Back to article page
