The adjusted hazard ratios for the highest tertile of achieved plasma levels were 0.98 for EPA and 1.02 for DHA.

The lack of significant hazard ratios suggests that high levels of EPA and DHA do not alter cardiovascular risk in this population.

Compared with corn oil, the adjusted hazard ratios for the highest tertile of achieved plasma levels were 0.98 (95% CI, 0.83-1.16; P = .81) for EPA, and 1.02 (95% CI, 0.86-1.20; P = .85 for DHA.
