FIGURE 1.

Cross-sectional comparisons of main plasma lipid parameters measured by NMR in young (n = 30) and older (n = 54) adults (left column), and the effects of 6 mo of placebo (n = 22, middle column) and n–3-PUFA supplementation (n = 22, right column) on triglycerides (A), esterified cholesterol (B), free cholesterol (C), phospholipids (D), apoA (E), apoB (F), and lipoprotein particle number (G). A total of 5 participants dropped out after randomization (2 placebo, 3 n–3 PUFA). Data are shown as mean ± SD. *Significant (P value < 0.05) differences between young and older adults observed at baseline. ^ΩSignificant differences between treatment groups found by ANCOVA.
