From: Lipid signatures of chronic pain in female adolescents with and without obesity
Healthy weight individuals with chronic pain have serum lipid profiles that match the obese and chronic pain obese groups. A Principal component analysis between serum of control (n=17), obese (n=16), pain non-obese (n=17), and pain obese (n=17) individuals. B Heat map of group averages showing lipid class distribution between control, obese, pain non-obese, and pain obese groups. C Lysophosphatidylinositol (LPI) species abundance in serum between control, obese, pain non-obese, and pain obese individuals. D Lysophosphatidylcholine (LPC) species abundance in plasma between control, obese, pain non-obese, and pain obese groups. n=16-17 per group, Data are presented as means ± SEM.
