From: Serum neutrophil gelatinase-associated lipocalin at inception of renal replacement therapy predicts survival in critically ill patients with acute kidney injury

Figure 3

Serum NGAL test characteristics at various cut-off values at initiation of RRT. Receiver-operator characteristic (ROC) curve showing the prognostic sensitivity and specificity of serum neutrophil gelatinase-associated lipocalin (NGAL) at initiation of renal replacement therapy (RRT) with regard to 14-day mortality (area under the curve (AUC) 0.74 (95% confidence interval (CI) 0.64 to 0.84) P < 0.0002). Cuboids indicate the cut-off values between NGAL quartiles (see also Figure 2 and Table 5).
