A: Venn diagram presenting differentially expressed oxidative stress genes across the three datasets. B: Consistency matrix clustering analysis. C: PCA analysis of oxidative stress clusters (PCA plot showing the distribution of samples in the first two principal components. Dashed circles represent clusters of samples identified based on their proximity in the PCA space, illustrating groupings with shared characteristics). D: Infiltration level of 23 immune-related cells in the CAS and control groups. E: Infiltration of 23 immune-related cells in the oxidative stress cluster. F: GO and KEGG analysis of differentially expressed genes in the oxidative stress cluster (BP: biological process CC: cellular component MF: molecular function). * p-value < 0.05; ** p-value < 0.01; *** p-value < 0.001; **** p-value < 0.0001
