Figure 2. Construction of a prognostic signature based on ARGs. (A) Forest maps of univariate Cox analysis. (B) a minimum value of λ was chosen as optimal. The black dot line on the left represents those 10 features that were reduced to 5 non-zero coefficient features by LASSO. (C) ARGs rank importance by random forest algorithm. (D) Venn diagram shows the intersection ARGs of Lasso and random forest algorithm.
