Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Parental consent and then randomised. Indomethacin or placebo prepared in yellow coloured syringes (indomethacin is a yellowish solution) prepared by hospital pharmacy. The randomisation list has been prepared in blocks in random order. It is held by the Clinical Trials Unit of the Hospital Pharmacy and the Chair of the Data Safety Monitoring Committee. The list is not available to clinicians or investigators. Randomisation is by allocating the baby the next number and faxing a perscription to Pharmacy. Pharmacy line up the number with the randomisation list and prepare the drug. The Clinical Trials Unit in Pharmacy acts as the central randomisation site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block randomisation stratified above or below 27 weeks.
Masking / blinding
Blinded (masking used)
