Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Eligible .participants will be allocated to one of three groups, normal diet, or one of two preparations of dairy lipids. Allocation is concealed by the use of numbered containers.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be undertaken using a variable block size schedule, based on computer generated random numbers.
Masking / blinding
