Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation of study supplements will be conducted by the Clinical Trials Pharmacist at Fiona Stanley Hospital. The randomisation schedule will be prepared using SealedEnvelope.com. This list will be provided to the manufacturer (off site) in order to create blinded, subject specific kits. Study supplements and placebo will be identical in appearance and non-identifiable.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block randomisation in variable block sizes will be conducted by the Fiona Stanley Hospital Clinical Trials Pharmacist and both participants and study investigators will be blinded to the intervention. The randomisation schedule will be prepared using SealedEnvelope.com. This list will be provided to the manufacturer in order to create blinded, subject specific kits.
