Calibration and discrimination of the AKI scores in predicting in-hospital mortality

Variable	Calibration			Discrimination
	Hosmer-Lemeshow χ2	df	P-value	AUROC ± SE	95% CI	P-value
ICA	0.688	2	0.709	0.730 ±0.041	0.649–0.810	< 0.001
KDIGO	0.798	2	0.671	0.752 ±0.040*	0.674–0.830	< 0.001

ICA – International Club of Ascites, KDIGO – Kidney Disease: Improving Global Outcomes, AUROC – areas under the receiver operating characteristic curves, SE – standard error, CI – confidence intervals.

^*P = 0.123 vs. ICA.
