ω-6 Arachidonic acid (ARA)	1.06	0.95	0.208
ω-3 Alpha-linolenic acid (ALA)	0.22	0.11	0.007
ω-3 Eicosapentaenoic acid (EPA)	0.15	0.06	3.76E-06
ω-3 Docosapentaenoic acid (DPA)	0.13	0.15	0.625

Note: Modified from Shih et al, 2016 (Mol Psychiatry). The mean of ω-6 to ω-3 ratios (upper) and the mean of individual fatty acids (lower). Concentration of each fatty acid was measured in the unit of μmol/L and reported as percentage of total plasma fatty acid. Statistical comparisons were tested by age-adjusted ANOVA. AN: Ill anorexia nervosa with BMI<=17.5
