Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The person who will determine if a subject is eligible for inclusion in the trial will be unaware, when this decision is made, to which group the subjects will be allocated. Allocation will be done by central randomisation by computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Eligible subjects will be randomly assigned to the docosahexaenoic acid (DHA) supplement or placebo using computer generated random numbers tables.
Masking / blinding
