PPI network and univariate COX. (a) Interaction network constructed with the nodes with interaction confidence value > 0.9. (b) The top 12 genes ordered by the number of nodes. (c) Univariate COX regression analysis with the 55 key genes, listing the top significant factors with P value < 0.10. (d) Venn plot showing the common genes shared by leading nodes in PPI and top significant factors in univariate COX. PPI protein–protein interaction.
