Neutrophil-lymphocyte ratio: A prognostic tool in patients with in-hospital cardiac arrest

Figure 1 Receiver operating characteristic curve of neutrophil-lymphocyte ratio in in-hospital cardiac arrest showing the true positive rate plotted against the false positive rate. The area under the curve value was 0.66 and cut off point of the neutrophil-lymphocyte ratio was determined to be 4.55 with a 73% positive predictive value, sensitivity of 82% and specificity of 42%.
