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. This evidence concerns the gene CD44 and gastric cancer.
