[Retracted] Cuproptosis-Related Genes CDK1 and COA6 Involved in the Prognosis Prediction of Liver Hepatocellular Carcinoma

Figure 3

Four prognostic genes were identified from the risk score model. (a) LASSO-Cox model fitting procedure. Each curve represents a gene. Plot the trend of each coefficient against the norm as varies. The norm is the total absolute value of the nonzero coefficients. (b) is selected by 10-fold cross-validation. (c) Risk score curves, patient survival, and heatmaps depicting the expression patterns of the four prognostic genes. (d) Difference in survival between high-risk and low-risk patients. Survival was poorer in the high-risk patient group. (e) Time-dependent ROC curve analysis of 1-, 3-, and 5-year overall survival predictions.
