**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.
