The efficacy of VNS is heterogeneous. A prediction model is needed to predict the efficacy before implantation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We collected data from children with DRE who underwent VNS implantation and received regular programming for at least 1\u2009year. Preoperative clinical information and scalp video electroencephalography (EEG) were available in 88 children. Synchronization features, including phase lag index (PLI), weighted phase lag index (wPLI), and phase\u2010locking value (PLV), were compared between responders and non\u2010responders. We further adapted a support vector machine (SVM) classifier selected from 25 clinical and 18 synchronization features to build a prediction model for efficacy in a discovery cohort (<jats:italic>n<\/jats:italic>\u00a0=\u00a070) and was tested in an independent validation cohort (<jats:italic>n<\/jats:italic>\u00a0=\u00a018).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In the discovery cohort, the average interictal awake PLI in the high beta band was significantly higher in responders than non\u2010responders (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). The SVM classifier generated from integrating both clinical and synchronization features had the best prediction efficacy, demonstrating an accuracy of 75.7%, precision of 80.8% and area under the receiver operating characteristic (AUC) of 0.766 on 10\u2010fold cross\u2010validation.
