The comparison of diagnostic performance of artificial neural network (ANN), multiple logistic regression (MLR), random forest (RF), and support vector machine (SVM) classifiers in the training cohort [(A) First Affiliated Hospital of Zhejiang University School of Medicine (FAH-ZJU)] and validation cohorts [(B) Shulan Health (Hangzhou) Hospital (SLH); (C) Lishui Central Hospital (LSCH)]. The performance was measured by the area under the receiver operating characteristic (AUROC) curve. ANN classifier (purple line), MLR classifier (green line), RF classifier (red line), SVM classifier (orange line).
