Translations:Omega-3 fatty acid/82/en

In contrast to dietary supplementation studies, there is significant difficulty in interpreting the literature regarding dietary intake of omega−3 fatty acids (e.g. from fish) due to participant recall and systematic differences in diets. There is also controversy as to the efficacy of omega−3, with many meta-analysis papers finding heterogeneity among results which can be explained mostly by publication bias. A significant correlation between shorter treatment trials was associated with increased omega−3 efficacy for treating depressed symptoms further implicating bias in publication.
