Validation of diagnostic hub genes. A Hub gene expression patterns in sepsis and healthy in GSE65682. B The heatmap shows the significantly different expression of hub genes between sepsis and healthy in GSE65682. C The ROC curve shows the diagnostic efficacy verification in GSE65682. D Kaplan–Meier survival curves by the expression level of hub genes. The sepsis patients were divided into high and low-expression groups based on the best cut-off value of gene expression
