Expression profiles of four important immune checkpoints in gastric cancer tissues, and their correlation with prognosis-related m6A-related lncRNAs. Differences in the expression of PD-L1, CTLA4, IL4I1 and IDO1 in different tissue types (A, D, G, J) and various subtypes (B, E, H, K). Correlation analysis of the relationship between the expression of the target genes PD-L1, CTLA4, IL4I1 and IDO1 and that of prognosis-related m6A-related lncRNAs (C, F, I, L). Red indicates positive relationships, while blue indicates negative relationships. *P < 0.05, ***P < 0.001
