Receiver-operating characteristic (ROC) curves for the artificial neural network (ANN) and logistic regression (LR) model for predicting reintubation (A), prolonged mechanical ventilation (B) and death (C). The difference was not significant. Area under the ROC (AUC) for (A) LR model = 0.62, ANN model = 0.65; (B) LR model = 0.67, ANN model = 0.72; and (C) LR model = 0.86, ANN model = 0.85
