Figure 1. Identification of co-expression modules associated with the clinical traits in the TCGA-LIHC dataset and two GEO datasets. (A, B) Analysis of the scale-free fit index for various soft-thresholding powers (β). (C, D) Dendrogram of all genes in the TCGA-LIHC dataset or GEO datasets clustered based on the 1-TOM matrix. (E, F) Correlation between modules and clinical traits (normal and tumor). Each cell contains the corresponding correlation coefficient (the upper number) and the P-value (the lower number).
