Correlation analysis of potential metabolites in stomach, medulla and cerebral cortex of rat. a correlation analysis of differential metabolites in GML-T1 subgroup; b correlation analysis of differential metabolites in GML-T4 subgroup; c correlation analysis of differential metabolites in EA-T1 subgroup; d correlation analysis of differential metabolites in EA-T4 subgroup. The red font represents different metabolites in gastric tissue; the green font represents different metabolites in medulla; the blue font represents different metabolites in cerebral cortex. The red area represents a positive correlation between the two metabolites, and the blue area represents a negative correlation
