Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
This was a cluster randomised controlled trial. Families were appraoched by their Maternal and Child Health nurse to take part in the study. Interested families were then cotacted by the research team to obtain informed consent. After all recruitment was complete, Maternal and Child Health centres (and their families) were randomly allocated to the intervention or control arm using a computer generated random number sequences for each Local Geovernment Area. An independent statisticain performed the randomisation and as all families and the researchers were unaware of intervention status at the time of recruitment and consent, allocation concealment was acheived.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using computerized sequence generation.
Masking / blinding
Open (masking not used)
