Prediction model of the persistence of pulmonary fibrosis. A Identified 4 Parameters that can distinguish between two groups. B The confusion matrix of the five-fold cross validation was used to validate the performance of the model. C Receiver operating characteristic curve which was used to evaluate the accuracy, Positive Predictive Value (PPV), Negative Predictive Value (NPV) and Sensitivity and Specificity of the model. True positive rate = Sensitivity; True negative rate = Specificity
