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

Variable	Cutoff value	AUC (95%  CI)	P  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%

Statistically significant values are in bold.

AUC, area under curve; PPV, positive predictive value; NPV, negative predictive value; GRWR, graft-to-recipient weight ratio.
