Medication randomisation is conducted by a computer at a central administration site where the trial medications are also labelled in numbered (coded) containers to maintain concealment for researchers.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computerised randomisation list was prepared by an independent researcher not involved in subject assessments.
