The 7-lncRNA signature can predict distinct survivals of ESCC patients with same TNM stage in the training cohort. The patients with same stage (II or III) were defined as high- or low-risk by the 7-lncRNA signature risk score and then analyzed with Kaplan–Meier survival curves. a Overall survival (OS) curves of 73 patients with high-risk or low-risk in the cases with TNM stage II in the training cohort. b Disease-free survival (DFS) curves in 73 patients with high-risk or low-risk in the cases with TNM stage II in the training cohort. c OS curves in 59 patients with high-risk or low-risk in the cases with TNM stage III in the training cohort. d DFS curves in 59 patients with high-risk or low-risk in the cases with TNM stage II in the training cohort. Note: in the Kaplan–Meier survival curves, the survival time unit is months
