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.
Isto é o que ían facer no seu ensaio. Ían coller 3 000 nenos, ían darlles unhas enormes  pílulas de aceite de peixe, seis ao día, e un ano máis tarde, ían medir  o rendemento escolar en exames e comparar ese rendemento co que eles calculaban que terían se non tomaran as pílulas.
