A Sample clustering of data set. B Scale-free soft threshold distribution. The vertical axis is Scale Free Topology Model Fit (signed R²). The higher the square of the correlation coefficient, the closer the network is to the scale-free distribution. The vertical axis of the right figure represents the mean value of all gene adjacency functions in the corresponding gene module. C Module clustering tree diagram. Genes are classified into modules by hierarchical clustering, with different colors representing different modules. D Correlation analysis result between WGCNA module and sample subtype. In each square, the upper number is the correlation coefficient cor and the lower number is the p value. The darker the color, the closer the correlation between modules with clinical traits
