Development and validation of a prediction model for moderately severe and severe acute pancreatitis in pregnancy

Figure 5 Development and assessment of the random forest algorithm in moderately severe and severe acute pancreatitis in pregnancy prediction. A: Relationship between out-of-bag error and number of trees. In total, 75 trees are selected to establish a random forest model; B: Feature importance; C: Receiver operating characteristic curves in the training set; D: Receiver operating characteristic curves in test set; E: Calibration curves of training set; F: Calibration curves of the test set.
