Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients who fulfill the eligibilty criteria and give their written informed consent to take part will be randomised centrally using a stratified minimisation method. Patients will be allocated open label aspirin or clopidogrel.
Randomisation will be performed at the National Health and Medical Research Council Clinical Trials Centre (NHMRC CTC)
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Masking / blinding
