Potential Novel Biomarkers of Obstructive Nephropathy in Children with Hydronephrosis

Figure 6

ROC analysis for the serum NGAL level in the detection of obstructive nephropathy (ON). (a) Patients with obstructive nephropathy (ON) vs. controls. AUC of 1.0, an optimal cut-off value of 0.0 ng/ml, sensitivity of 100%, specificity of 100%. (b) Patients with obstructive nephropathy (ON) vs. patients with hydronephrosis without obstructive nephropathy (HN without ON). AUC of 0.6, an optimal cut-off value of 0.145 ng/ml, sensitivity of 100%, specificity of 12.5%.
