Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be assigned random numbers using a random number generator program. These random numbers will be sent to the clinic, and the randomisation table will be kept blind by the organisation from the investigators during the research period. Allocation done by department independent of the study centre.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation)
Masking / blinding
Blinded (masking used)

Statistical methods / analysis
Ultimately, 60 participants will be randomised into two groups of 30 (minimum 20) each.The plan is to aim for 30 subjects allocated to each group, that allows the team to set the statistical power at a minimum of 80% which is a desired minimum benchmark. All statistical evaluation and analyses will be undertaken independently by the Department of Mathematical Sciences of the Auckland University of Technology.
