Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A computer-generated list of random numbers is used to allocate participants to the control or intervention group. Assignment to groups is undertaken by the supplier of the portable cylinders, and is thus concealed from the investigators.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Allocation to the intervention or control group is undertaken on an odd or even number basis from a list of random numbers, which was computer-generated, using Microsoft Excel software.
Masking / blinding
