Identification of key genes in ischaemic stroke by machine learning. A In total, 25 key genes in ischaemic stroke were identified by a LASSO regression. B In total, 40 key genes in ischaemic stroke were identified by the SVM-RFE algorithm. C Venn diagram of the genes extracted from the LASSO and SVM-RFE methods. LASSO, least absolute shrinkage and selection operator; SVM, support vector machine-recursive feature elimination
