Construction of a gene risk score model in the ACRG cohort. A Prognostic analyses for 23 cholesterol metabolism genes using univariate Cox regression model. B Screening of prognostic model genes using LASSO regression. C Cross-validation of LASSO regression parameter selection. D Distribution of the risk score and survival status of 300 patients in the ACRG cohort. E Survival analysis of high- and low-risk patients based on OS (log-rank test). F Risk scores of CMT1 and CMT2 (Wilcoxon test). G Correlation heatmap of the risk score and prognostic model genes with immune cell infiltration and immune checkpoint genes
