Neutrophil-to-lymphocyte ratio predicts acute kidney injury occurrence after gastrointestinal and hepatobiliary surgery

Figure 1 Receiver operating characteristic analysis for optimal cutoff values of neutrophil-to-lymphocyte ratio. Area under the receiver operating characteristic curve: 0.6338. The optimal cutoff value of neutrophil-to-lymphocyte ratio was 8.38. NLR: Neutrophil-to-lymphocyte ratio; ROC: Receiver operating characteristic.
