Numbered containers with central randomisation by computer with code held by one designated person not involved with any other aspects of the trial.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Allocation used permuted blocks to maintain treatment balance over time, and blocks will be a random mixture of sizes to assist allocation concealment
