Stratified analyses according to dietary ALA-above (n = 128) and below (n = 127) median intake of ALA (2.06 g/day). BOLD = p < 0.05, * = p < 0.01, ** = p < 0.001. AA: arachidonic acid; ALA: α-linolenic acid; DHA: docohexaenoic acid; EPA: eicosapentaenoic acid; LA: linoleic acid; %TPFA: percentage of total plasma fatty acids.
