Displayed are the log2 transformed relative concentrations of Palmitoylethanolamide and the phospholipid PE(17:1(9Z)18:0), which showed the strongest univariate group differences. The left panel visualizes the differences between PTSD patients and controls, while the right panel displays the correlation with PTSD symptomatology assessed with the Clinician Administered PTSD Scale (CAPS) Score.
