Fig. 3From: Identification of a 4-lncRNA signature predicting prognosis of patients with non-small cell lung cancer: a multicenter study in ChinaThe 4-lncRNA signature predicted different survivals rates in patients with NSCLC at the same TNM stage. Based on the 4-lncRNA signature risk score, patients with NSCLC at the same stage were divided into high- and low-risk groups. Kaplan–Meier survival analysis was performed to estimate patients’ survival rate in the discovery cohort. NSCLC patients with high risk (based on the 4-lncRNA signature) showed significantly poorer OS (left panel) and DFS (right panel) rates than those in low-risk group at a stage I (n = 87), b stage II (n = 32) and c stage III (n = 84)Back to article page
