Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients will be enrolled from the primary investigators clinic. If willing to volunteer they will have an identifier number generated by computer program to ensure anonymity. The identifier numbers will then be randomized by a third party using a random sequence generator. Concealment of allocation will be accomplished by sealed opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
We will use block randomization. 40 patients will be recruited and allocated equally to each group (allocation ratio 1:1).
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
