Determination of prognostic ferroptosis- and immune-related genes. (A) 100-fold cross-validation for choosing tuning parameters of the Least Absolute Shrinkage and Selection Operator (LASSO) model. The LASSO coefficient profiles of prognostic genes. (B) Prognosis-related genes screened further using a stepwise Cox proportional hazards regression model. (C) Distribution of the risk score and gene expression profile. The risk factor heatmap shows expression abundance of four hub genes in the high-low riskscore group.
