A 2-lncRNA signature for LUAD patient prognosis. Kaplan-Meier estimates the overall survival using the 2-lncRNA signature in the a training dataset, b GSE50081 and c GSE31210. All the P values of Kaplan-Meier analysis were calculated using log-rank test. d The lncRNA C1orf132 was down-regulated in the high-risk patients. e The lncRNA TMPO-AS1 was up-regulated in the high-risk patients
