Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A central randomisation centre is located at the Austin Hospital Pharmacy Department. The Pharmacy Department at each centre will maintain an additional log of patient details and treatment allocation for purposes of cross checking or unblinding of patients in the event of a serious adverse outcome. Any patients who are randomised, but do not follow protocol for whatever reason, are still followed up by the intention-to-treat principle.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Following the informed consenting process, participants are assigned consecutively to next study allocation (treatment or placebo). The allocation log was generated using random number generating software.
