Correlation network between OS-AS events (a) and DFS-AS events (b) and prognostic SFs in HP⁻ GC. The majority of prognostic AS events with poor prognosis (red dots) were positively (green lines) correlated with the expression of SFs, while the majority of AS events with good prognosis (green dots) were negatively (red lines) correlated with the expression of SFs. AS: alternative splicing; OS: overall survival; DFS: disease-free survival; SF: splicing factor; HP⁻ GC: Helicobacter pylori-negative gastric cancer. HP⁻ GC: Helicobacter pylori-negative gastric cancer
