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)
Numbered containers, blinded contents of which are prepared by a research pharmacist otherwise not involved with the trial. Treatment assignments kept secure at Pharmacy, unavailable to researchers involved with trial recruitment, execution, data collection and data entry until conclusion of trial data collection and entry.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Batches of 16, with 8 amethocaine and 8 placebo assignments in each.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Single group
Other design features
