Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Medication will be prepared by a doctor not involved with study participants. The medication will be then administered by a study nurse who is unaware of the contents. Thus all study personnel with patient contact will be blinded.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer-generated random numbers in variable blocks.
Masking / blinding
Blinded (masking used)
