PRCTC: a machine learning model for prediction of response to corticosteroid therapy in COVID-19 patients
Figure 2. PRCTC achieved a prompt performance in evaluation on the validation datasets. (A–C) showed ROC curve and AUC of SVM, LR, GBDT, KNN, and NN in training cohort, internal validation cohort, and external validation cohort, respectively. Abbreviations: PRCTC, prediction of response to corticosteroid therapy in COVID-19 patients; ROC, receiver operating characteristic curve; AUC, area under the curve; SVM, supported vector machine; LR, logistic regression; GBDT, gradient boosted decision tree; KNN, k-nearest neighbor; NN, neural network.
