Serial measurement of urinary NGAL during CVVHDF. Urinary NGAL level was measured at initiation, 24 h, and 48 h after CVVHDF initiation. The results are shown in absolute value (A), and relative fold change from the initiation (B). A In CVVHDF nonsurvivors, urinary NGAL levels significantly increased at 24 and 48 h after CVVHDF initiation. Conversely, this increase was not observed in survivors. B The relative change of urinary NGAL from the CVVHDF initiation was significantly higher in CVVHDF nonsurvivors than in CVVHDF survivors. *, p < 0.05; **, p < 0.01; n.s., not significant
