  1. A Kruskal-Wallis analysis of variation (ANOVA) test followed by a post-hoc Mann–Whitney-Wilcoxon test was used to examine each fatty acid in the three ethnicities. Ethnic groups with different superscript letters (e.g. a or b) are statistically different (P < 0.05) for a given parameter. All data is represented as mean μg/mL ± standard error.
