Ratio of n−6 PUFAs to marine-derived n−3 PUFAs
Men: range, 12–53,381; median, 157; women: range, 16–61,662; median, 169	0.04 (−0.04, 0.12)	0.21 (0.10–0.32)

¹All values are partial Spearman's correlation coefficients; 95% CIs in parentheses. PGEM, prostaglandin E₂ metabolite.

²Marine-derived n−3 PUFAs = EPA + docosapentanoic acid + DHA.
