The effect of DHA+EPA supplementation on plasma fatty acid concentrations as a percent of total fatty acids. (A) DHA concentrations as a percent of total fatty acids in treatment and placebo groups from baseline through week 33. (B) EPA concentrations as a percent of total fatty acids in treatment and placebo groups from baseline through week 33. (C) DPA concentrations as a percent of total fatty acids in treatment and placebo groups from baseline through week 33. (D) ARA concentrations as a percent of total fatty acids in treatment and placebo groups from baseline through week 33. DHA, docosahexaenoic acid; EPA, eicosapentaenoic acid; DPA, docosapentaenoic acid; ARA, arachidonic acid; p-values show significance between groups (*) and within groups from baseline values (+) according to repeated measures ANOVA and estimated marginal means; p-values: * + p < 0.05; ** ++ p < 0.01, *** +++ p < 0.001.
