Based on these 22 lncRNAs, LASSO COX regression analysis was performed, and 13 lncRNAs were further identified: TNFRSF10A-AS1, TMEM132D-AS1, MIR3142HG, LINC01980, LIMS1-AS1, CD44-AS1, AP000695.2, AL355574.1, AC124319.1, AC090204.1, AC026369.2, AC026368.1, and AC022762.2, and the prognostic risk-assessment model was then constructed for gastric cancer Figure 2F. The lncRNAs used to construct the model are presented in Table 1. The gene discussed is TNFRSF10A; the disease is gastric cancer.
