a Clustering of 75 ovarian cancer samples and corresponding clinical information where the numeric information is larger, the darker color is shown. b Cluster dendrogram in which branches correspond to gene modules based on topological overlaps and each piece of the leaves represents a gene. c The scale-free index and the average connectivity calculated under different β. The approximate scale-free topology can be achieved at a soft threshold power of 3. d Histogram of connectivity distribution and checking the scale-free topology when β = 3
