Construction of the prognostic model based on the nine-lncRNA signature in the training cohort. A a. Risk score distribution of patients with GC using the nine-lncRNA signature. b. Scatter plots showing the survival of GC patients. c. Heatmap of the expression of the nine lncRNAs in the high-risk and low-risk groups. B Kaplan‒Meier survival curves showing the difference in overall survival (OS) between low-risk and high-risk patients. C Kaplan‒Meier survival curves showing the difference in progression-free survival (PFS) between low-risk and high-risk patients
