The AUC of Nomogram, APSIII and SAPSII in training and validation cohort

Predictive Model		AUC	Delong’s test (Z)	p-value
Training Cohort	Nomogram	0.843 (0.792, 0.893)
	APSIII	0.764 (0.711, 0.817)	2.19	0.03
	SAPSII	0.764 (0.712, 0.816)	2.30	0.02
Validation Cohort	Nomogram	0.891 (0.837, 0.946)
	APSIII	0.782 (0.698, 0.867)	2.51	0.01
	SAPSII	0.706 (0.617, 0.796)	3.60	< 0.001

AUC area under the curve; APSIII Acute Physiology Score III; SAPSII Simplified Acute Physiology Score II. The Delong’s test demonstrated a significant difference in AUC between the APSIII, SAPSII score and the Nomogram model
