Construction of risk models. (a) Univariate regression analysis of CD8-DEGs. (b) Plot of the out of bag (OOB) prediction error rate for each tree constructed in the CD8-DEG model (left panel). Plot of variable importance in the CD8-DEG model (right panel). (c, d) ROC curves showed the predictive efficiency of the CD8-DEG risk score for 1-, 3-, and 5-year survival in the training and validation cohorts.
