Receiver-operating characteristic analysis of the artificial neural network in comparison with the model of the end-stage liver disease performance

	ANN	MELD score	p Value*
	AUC	AUC	p Value*
ANN, artificial neural networks; AUC, area under the curve; MELD, model for end-stage liver disease.
*p values of each ANN subgroup compared with the MELD score of the same subgroup (Hanley–McNeil method).
Training/cross validation	0.98	0.86	0.002
Internal validation	0.95	0.85	0.032
External cohort	0.96	0.86	0.044
