<p>The bar plot shows the enrichment scores (−log10 (<i>P</i>-value)) value of the significant enrichment pathways. The white bar shows the pathway in which the up-regulated mRNAs were found to be involved and the blue bars show the pathways in which the down-regulated mRNAs were found to be involved. Pathway analysis involves mapping genes to KEGG pathways. The <i>P</i>-value denotes the significance of the correlation between the pathway and the conditions. Most of the shown here are related to metabolism, which indicates that the varicose veins may be a metabolic disease.</p
