Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A black sticker obscures the next treatment group and is only removed after enrolment
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Children are randomised within strata of age (<6 years or >= 6 years) and site of enrolment. They are subsequently allocated to the next treatment regimen on a list, which was been previously generated, in random order, at a remote site (Queensland Institute of Medical Research). The method of randomisation was permutated block design by computer generation.
Masking / blinding
