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.
Donc, c'est ce qu'ils allaient faire dans leur test. Ils ont pris 3 000 enfants, ils allaient leur donner ces énormes pilules d'huile de poisson, six par jour, et un an plus tard, ils allaient mesurer leur performance aux examens scolaires et comparer leur performance avec ce qu'ils avaient prédit que leur performance serait s'ils n'avaient pas pris les pilules.
