Figure 4. Common hub genes and pathways in differentiating plaque sets and poor prognosis sets. A five-set Venn diagram showing a combination of all differentially expressed genes of GO processes and KEGG pathways in differentiating plaque sets and poor prognosis sets. A total of 4 common genes were identified. Fold change and P value of the 4 common genes in differentiating plaque sets and poor prognosis sets. They are all upregulated genes. Four-way Venn diagram of GO processes and KEGG pathways identified in differentiating plaque sets and poor prognosis sets. A total of 4 GO processes and 9 KEGG pathways were identified in common between the training set and differentiating plaque sets. Details of the common pathways from Venn diagram analysis. FC1: fold change in differentiating plaque sets; FC2: fold change in poor prognosis sets.
