A. PCA results for the combined expression profile before and after Combat. B. Volcano plot displaying DEGs, with fold change > 1.5 and adjusted p-value < 0.05. C. Heatmap of the top 100 DEGs ranked by adjusted p-values, indicating gene expression trends in different PBMC. DEGs: differentially expressed genes; PCA: principal component analysis; PBMC: peripheral blood mononuclear cellBack to article page
