Fig. 1

Heatmap visualization of phospholipids and neutral lipids in plasma of ME/CFS patients and controls. The heatmaps represent the average of relative concentrations to male controls of the total level of each lipid classes (left), lipids stratified by their level of unsaturation (middle) and lipids containing arachidonic acid (AA) or docosahexaenoic acid (DHA) (right) in each group. Black asterisks show significant differences between male and female ME/CFS patients and controls (p < 0.05) and red asterisks show significant differences between males and females within the same diagnosis status (p < 0.05)
