Absolute (nmol/ml) and relative (% TFA) measures of fatty acids in umbilical cord red blood cells (RBCs) and plasma at birth

Fatty acidsFish oil (n=27)*Placebo (n=26)*
Values are median (range).
*Blood samples were not obtained from four infants in the fish oil group and three infants in the placebo group at birth.
AA, Arachidonic acid; DHA, docosahexaenoic acid; EPA, eicospentaenoic acid; % TFA, percentage of total fatty acids.
