The three-lncRNA signature predicts overall survival and disease-free survival of patients with ESCC. Kaplan–Meier survival curves of patients are classified into high- and low-risk groups using the three-lncRNA signature in the (a) training set (n = 77), (b) test set (n = 61) and (c) independent set (n = 119). P-values were calculated by the log-rank test. OS, overall survival; DFS, disease-free survival
