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

Figure 4

Prognostic impact of the model in clinical characteristics. The correlation of the 7-gene signature-based risk score with the TNM stage was analyzed in the (a–c) training set and (d–f) testing set. (g) OS curves were plotted for validation of the predictive ability of the 7-gene signature-based risk score in patients with different age and TNM stage.
