Feature selection and predictive performance of the DIS. (a) LASSO coefficient profiles of the fractions of 15 immune cell types. (b) Tenfold cross-validation for parameter selection in the LASSO model. (c) Results of Boruta analysis in the training cohort. Color coding according to green = selected, yellow = tentative, and red = rejected. ROC curves of DIS in the (d) training, (e) internal validation, and (f) external validation cohorts. Note: DIS: diagnostic immune score; AUC: area under the ROC curve.
