Volcano plot of differential gene expression of cachectic vs. non-cachectic COPD patients from COPDGene. The plot shows the log2 fold change on the x-axis and the unadjusted p-value on the y-axis (on the -log10 scale). Blue dots represent genes with a fold changed greater than or equal to + 1 and a p-value < 0.05
