Establish and validate an artificial neural networks model used for predicting portal vein thrombosis risk in hepatitis B-related cirrhosis patients

Figure 5 The cumulative probabilities of portal vein thrombosis of our model at 3/5 years in the training and validation data sets. A: The cumulative curve for predicting the occurrence of portal vein thrombosis (PVT) using the artificial neural network (ANN) model within three years in the training group; B: The cumulative curve for predicting the occurrence of PVT using the ANN model within five years in the training group; C: The cumulative curve for predicting the occurrence of PVT using the ANN model within three years in the validation group; D: The cumulative curve for predicting the occurrence of PVT using the ANN model within five years in the validation group.
