a Using receiver operating characteristic (ROC) curve and area under the receiver operating characteristic curve (AUC) to compare the discriminant ability of four models based on DRM-COVID-19, incubation period, clinical, and CT scores. b Due to the imbalance of the data set, the precision-recall (PR) curve was used further to evaluate the classification ability of the predictive model; AUCPR (0.934) indicated the model performed well in predicting case classification. c The accuracy, precision, recall, and F1 score values were 0.933, 0.829, 0.935, and 0.879, respectively. d In the PR curve of DRM-COVID-19, the confusion matrix was constructed.
