Hub genes for pediatric sepsis diagnosis. a Venn diagram showed the intersection of diagnostic markers obtained by the three algorithms; b Nomogram is used to predict the occurrence of pediatric sepsis; c DCA curves d the ROC curve of the diagnostic efficacy verification; e Boxplot showed the expression of hub genes between pediatric sepsis group and control group in validation set; f The ROC curve of the diagnostic efficacy verification in validation set. SVM-RFE support vector machine-recursive feature elimination, RF random forest, LASSO least absolute shrinkage and selection operator, AUC area under curve, ROC receiver operating characteristic curve, DCA decision curve analysis
