Allocation to intervention
Randomised controlled trial
Query!
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.
