Co-expression network, protein-protein interactions (PPIs) and univariate survival analysis for 77 genes in the brown module. a The co-expression network for 77 genes in the brown module associated with the pathological stage. The red nodes represent hub genes obtained by WGCNA. b STRING database identified that 37 genes compactly interacted with each other. c A forest plot illustrating the independent prognostic value of 77 genes obtained from univariate Cox regression analysis. The points show the HRs and the corresponding lines show the 95% confidence intervals
