Performance comparison of artificial neural network and logistic regression models for predicting reintubation, prolonged mechanical ventilation and death

Outcomes	Accuracy	Sensitivity	Specificity	AUC	AUC p-value
Reintubation:
Artificial neural network	0.63	0.64	0.63	0.65 (0.53–0.77)	0.013
Logistic regression	0.60	0.64	0.60	0.62 (0.50–0.75)	0.049
Prolonged mechanical ventilation:
Artificial neural network	0.63	0.76	0.62	0.72 (0.64–0.81)	7.11 × 10–7
Logistic regression	0.63	0.64	0.63	0.67 (0.57–0.78)	0.0016
Death (considering PMV):
Artificial neural network	0.77	0.91	0.76	0.85 (0.80–0.91)	0
Logistic regression	0.77	0.82	0.77	0.86 (0.79–0.93)	0

AUC – area under the receiver operating characteristic (ROC) curve, PMV – prolonged mechanical ventilation
