Figure 2. Construction of a GC risk model based on autophagy-related lncRNA pairs. (A, B) Univariate Cox regression and LASSO algorithm were utilized to identify optimal autophagy-related lncRNA pairs associated with GC survival. The optimal gene pairs were subjected to the Cox proportional hazard model using (C) univariate and (D) multivariate analyses. A prognostic model was constructed using a stepwise regression method. Hazard ratios were visualized in forest plots.
