The PPI network of the co-DEGs, the hub gene network, the correlation analyses among the hub genes, and the expression profile analyses of the hub genes. A The PPI network includes 54 edges and 26 nodes. B The hub gene network (S100A12, CXCR2, MNDA, S100A8, NCF2, CCR2, S100A9, PTPRC, CCL20, and CXCL1). C The Circos plot showing that there are intense correlations among the hub genes in GSE79768. D Significant correlations among the hub genes were also performed in the GSE63067 dataset. E The expression profile of the hub genes for the control and AF samples in GSE79768. F The expression profile of the hub genes for the healthy group and NAFLD samples in GSE63067. Red indicates that gene expression is upregulated, and blue indicates that gene expression is downregulated. In the same color, the darker the color, the more significant it was
