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.
Ecco cosa facevano nel loro esperimento. Hanno preso 3000 bambini, gli hanno dato tutte queste pillole a base di olio di pesce, sei al giorno, e un anno dopo, hanno misurato i loro risultati scolastici agli esami confrontandoli con gli esami scolastici con la loro previsione di risultato su questi esami se non avessero preso le pillole.
