a Volcano plot showing the alignment between DESeq p values versus log2 fold changes of CFS patients against healthy controls. Red points indicate DEGs with a log2 fold change >0.2 and p < 0.0016 (Table 2). b Hierarchical clustering of all 176 differently expressed genes. The heatmap was constructed based on the deviation of gene expression levels of individual sample from averaged gene expression across all samples (Table 2). The color code for variance value is shown in the upper right corner of the panel
