Table 3 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	95% CI	AUC	95% CI
Training/cross validation	0.98	0.94 to 0.99	0.86	0.80 to 0.91	0.002
Internal validation	0.95	0.86 to 0.99	0.85	0.74 to 0.96	0.032
External cohort	0.96	0.91 to 0.98	0.86	0.79 to 0.91	0.044

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).
