Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients will be randomised by a blinded health professional through the secure trial website, coordinated by an independent trial centre. Random number sequences will correspond to serial numbers on concealed study packaging.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Stratified randomisation by the online randomisation website (ccre.med.monash.edu.au/TEDYrand).
Masking / blinding
