Figure 5. Selecting the appropriate beta value to build the cluster tree. (A) Sample tree and phenotype relation heat map, we selected the cutoff point of 130 and obtained 198 clinical samples. The phenotype includes overall survival, overall state, age, gender, clinical stage, and the expression level of TPX2, TXNRD2 and SLC6A20. The larger the value, the darker the color. (B–E) We built scale-free co-expression networks. The best soft threshold was 5, R-squared = 0.96.
