Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Volunteers assigned a unique alpha-numeric identifying code after informed consent obtained.
Allocation was conducted by the Principal Investigator or senior co-investigator on site. As it was an open/unblinded trial there was no concealment of allocation involved. Once allocation was completed the files were held at a central administrative site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
At the beginning of each recruiting day a coin was tossed to determine which drug the initial entry would take then the remainder of volunteers were allocated drug according to a predetermined ratio
Masking / blinding
Open (masking not used)
