Figure 3From: Plasma neutrophil gelatinase-associated lipocalin predicts acute kidney injury, morbidity and mortality after pediatric cardiac surgery: a prospective uncontrolled cohort studyROC analysis of 2-hour NGAL at three cut-offs. Shown is a ROC curve analysis of the 2-hour plasma NGAL measurements with the three cut-off levels from Table 2 indicated as filled squares annotated with the corresponding NGAL concentration. The area under the curve was 0.96 (95% confidence interval 0.94 to 0.99). NGAL, neutrophil gelatinase-associated lipocalin; ROS, receiver operating characteristic.Back to article page
