Hub gene analysis a GO pathway diagram, consisting of three parts: genes, LogFold Change (representing the fold change of genes for sorting and color-coding gene blocks), and other columns representing GO terms. Different connections between genes indicate their involvement in specific GO terms. b Principal component analysis (PCA) plot. The coordinates PC1 and PC2 represent the first and second principal components (i.e., latent variables explaining the differences). Points represent samples, and different colors represent different groups. c Gene ridge plot. The x-axis represents gene expression levels, and the shape of the ridges represents the distribution of data within each group, with the height indicating the number of samples corresponding to the gene expression level
