Plasma NGAL values in de novo AKI and AKI superimposed on CKD . Values of plasma neutrophil gelatinase-associated lipocalin (NGAL) for four groups (CKD(-)AKI(-) (n = 54), CKD(-)AKI(+) (n = 20), CKD(+)AKI(-) (n = 39), and CKD(+)AKI(+) (n = 33)). #, P <0.05 vs. CKD(-)AKI(-); *, P <0.05 vs. CKD(+)AKI(-).
