Each participant had a specific number and the treatments were supplied by the sponsor in numbered tubes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants were assigned to a number on a first come, first entered basis. (i.e. the first recruited person was recorded as number 1)
