Abstract

BACKGROUND: NEURAPRO was a multicenter, placebo-controlled trial of long-chain omega-3 polyunsaturated fatty acids (n-3 PUFAs) (fish oil) in 304 individuals at ultra-high risk for psychotic disorders. The study failed to show benefits of n-3 PUFAs over placebo. Although the randomized controlled trial design is placed at the top of the evidence hierarchy, this methodology has limitations in fish oil randomized controlled trials, as not only is the test agent present in the intervention group, but also n-3 fats are present in the diet and the body tissue of all participants. METHODS: Analysis of biomarker data (eicosapentaenoic acid [EPA], docosahexaenoic acid [DHA], n-3 index, EPA+DHA) colle..
