(A) Univariate Cox analysis evaluates the prognostic value of the ICDRGs in terms of OS; (B) LASSO regression analysis to develop the prognostic model; (C, D) PCA and t-SNE analysis in the all TCGA set. The nine model genes did a more accurate job of dividing patients into two groups; (E–G) The survival status, risk score, and model gene expression in the TCGA all, train and validation sets.
