Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Central randomisation by Mater Pharmacy. Researchers, who were blinded to randomisation, were provided with a ⿿randomisation schedule⿝. Stratified for gender and lung function each participant was allocated the next pharmacy study number from the randomisation schedule. Each pharmacy involved in study was provided with a randomisation code, where by each study number was allocated to either arm A or arm B of the trial. All labelling of A or B was removed from packaging prior to dispensing so that all participants received identical medication packages, regardless of treatment arm.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Microsoft Excel was used by the Mater Pharmacy to generate the random allocation sequence. Randomisation is in blocks, stratified for gender and lung function.
