Fig. 4From: Lung transcriptomics reveals the underlying mechanism by which aerobic training enhances pulmonary function in chronic obstructive pulmonary diseaseVenn diagrams of DEGs were identified in different comparisons, including (A) upregulated DEGs and (B) downregulated DEGs. The venn diagrams revealed overlapping DEGs in the comparisons between groups, including three upregulated DEGs and one downregulated DEGs in the three comparisons.
