Development and Validation of a Seven-Gene Signature for Predicting the Prognosis of Lung Adenocarcinoma

Figure 2

Evaluation of the 7-gene signature-based model in predicting the prognosis of LUAD patients. (a, b) The survival time between the patients of the high- and low-risk groups within the training set and testing set was analyzed by Kaplan-Meier analysis; (c–e) heat map for the 7 genes, as well as the risk score distribution and survival of patients in the training set; (f, g, h) heat map for the 7 genes, as well as the risk score distribution and survival of patients in the testing set; (i, j) ROC curves of the 7-gene signature-based model in two sets.
