From: Identification of a ferroptosis-related gene signature predictive model in colon cancer
Establishment of a prognostic gene signature by LASSO regression analysis. a LASSO coefficient profiles of the 10 genes in colon cancer samples. b A coefficient profile plot was generated against the log (lambda) sequence. Selection of the optimal parameter (lambda) in the LASSO model for colon cancer. c The distribution and median value of the risk scores in the Cancer Genome Atlas (TCGA) cohort. d PCA plot of the TCGA cohort. e t-SNE analysis of the TCGA cohort. f OS status, OS, and risk score in the TCGA cohort. g Kaplan–Meier curves for the OS of patients in the high- and low-risk groups in the TCGA cohort. h AUC of time-dependent ROC curves verified the prognostic performance of the risk score in the TCGA cohort
