Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation will be performed using sequentially numbered, opaque, sealed envelopes, stratified for the presence or absence of a TSAT less than or equal to 20%.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The sequence of interventions was obtained from a computer-generated random number list in permuted blocks provided through the Australasian Kidney Trials (AKTN) network.
Masking / blinding
Open (masking not used)
