n = 56 participants completed Baseline and Final questionnaires (omega-3 dietary intake, questionnaire data), and blood draws for clinical data analysis. n = 55 participants completed Baseline and Final blood draws for RBC fatty acid (FA) data analysis. Using a ROUT outlier analysis, 4 individuals were removed from the TAG data, and 1 individual was removed from the Cholesterol, %EPA, and %ALA data. For the omega-3 dietary intake, clinical and RBC FA data, values represent mean ± SEM. The questionnaire data is represented as the proportion of participants who answered “yes”. Percentages are provided in parentheses. A repeated measures 2-way ANOVA was used to evaluate the effects of Group (Genetic vs. Non-Genetic) and Time (Baseline vs. Final), as well as the Group × Time interaction. p-values < 0.05 are shown in bold. RBC FA, clinical and questionnaire data were adjusted for multiple comparisons using a Benjamini Hochberg approach. Values significant after correction for multiple testing are indicated with a *.
