Renal Dysfunction after Living-Donor Liver Transplantation: Experience with 500 Cases

Table 3

Accuracy of operative time, blood loss, and GRWR in predicting renal impairment at one year after liver transplantation.

Variable	Cutoff value	AUC (95CI)	Value	Sensitivity	Specificity	PPV	NPV
Operative time (minutes)	≥ 714	0.888 (0.819-0.958)	< 0.0005	90.9%	84.2%	33.3%	99.1%
Blood loss (ml)	≥ 7750	0.730 (0.652 – 0.809)	< 0.0005	72.7%	77.1%	21.6%	97.0%
GRWR (negative predictor)	≥ 0.91	0.811 (0.745 – 0.878)	< 0.0005	32.6%	93.5%	81.0%	01.5%
