Table 1 Cut-off Values for the Fatty Acid Ratios which place the Levels of Total Omega-3 Fatty Acids, DHA, and EPA+DHA in the 'Lower Risk' Categories with 95% Confidence Level

From: Correlation of omega-3 levels in serum phospholipid from 2053 human blood samples with key fatty acid ratios

  1. * The 'lower risk' categories for total omega-3, DHA, and EPA+DHA levels (as % of total fatty acids in serum phospholipid) are for coronary heart disease in the case of total omega-3 and DHA [3, 4] and for fatal ischemic heart disease in the case of EPA+DHA [4, 5].
