Comparison of receiver operating characteristic curves for RDW and PIM-2.

Abstract

<p>Receiver operating characteristic (ROC) curves for RDW (solid black line), PIM-2 (dashed maroon line) and the combination of PIM-2 and RDW (dotted green line) to predict all-cause PICU mortality. There was no difference between the AUROC for RDW and PIM-2 (p = 0.18). The addition of RDW to PIM-2 did not increase the AUROC compared to PIM-2 alone (p = 0.49). AUROC is the area under the ROC curve.</p
