Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation was concealed. All product had previously been de-idenitified, numbered and packaged at a central adminstration site according to the allocation schedule. The Investigator allocated the next available number to each new participant. In the case of medical emergency the treatment code could be accessed for a single subject without breaking the blind for other subjects.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer generated block randomization schedule.
Masking / blinding
Blinded (masking used)
