Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Medication was prepared by a nurse not involved with study participants. The medication was then administered by a study doctor who was unaware of the contents. All study personnel with patient contact were 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)
