Erythrocyte fatty acid composition. Median and interquartile ranges shown for the three arms at baseline, day 28, and day 84. Graphs show (clockwise from top left) DHA, EPA, AA, n-6:n-3 ratio in LC-PUFA, and total LC-PUFA (n-6 and n-3). For between-arm comparisons (ANOVA) at each time point: *P ≤0.05; **P ≤0.01; ***P ≤0.001. For within-arm comparison (sign test) to baseline values: † P ≤0.05. LC indicates species with carbon chain >18.
