Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Yes. Sealed, opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Yes. Permuted blocks by gender. Assignments will be enclosed in sealed, opaque envelopes in bundles of males and females. To improve assignment acceptance, subjects will select and open an envelope from the stack of their gender. (Blue for Males, Pink for females)
