Receiver operating characteristic (ROC) curve for support vector machine with radial basis function kernel function algorithm with 10-fold cross-validation in the prediction of poststroke depression (PSD) occurrence (control vs. PSD, (A)), support vector machine linear algorithm with five-fold cross-validation in the prediction of PSD prognosis (improved vs. not improved, (B)), and ROC curve for logistic regression analysis in the prediction of PSD occurrence (C) and PSD prognosis (D).
