Identification of an Exosome-Related Signature for Predicting Prognosis, Immunotherapy Efficacy, and Tumor Microenvironment in Lung Adenocarcinoma

Figure 2

Validation of the prognostic signature for LUAD patients in the testing set and two external validation sets. Kaplan–Meier curves showed that the high-risk group had worse overall survival (OS) than the low-risk group in the testing set (a), GSE68465 set (c), and GSE72094 set (e). ROC curves and their AUC values represented 1-, 3-, and 5-year predictions in the testing set (b), GSE68465 set (d), and GSE72094 set (f).
