So this is what they were going to do in their trial: They were taking 3,000 children, they were going to give them these huge fish oil pills, six of them a day, and then, a year later, measure their school exam performance and compare their performance against what they predicted their exam performance would have been if they hadn't had the pills.
O que é que iam fazer nesse teste? Iam pegar em 3000 crianças, davam-lhes seis destas enormes cápsulas de óleo de peixe, por dia. Um ano depois, mediam o rendimento escolar nos exames e comparar com o rendimento escolar que previam que teria sido, se não tivessem tomado as cápsulas.
