Results of the meta-analyses of n-3 fatty acid GWAS; main results with standard adjustments described in Methods, and additional results further adjusted for one other fatty acid or for selected SNPs.
†Adjustments of the cohort-specific GWAS; the main model included age, sex, and if appropriate study site and principal components to account for population structure.
‡Adjustment in addition to main model adjustments.
