Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A research assistant will randomly allocate the participants to either real or sham acupuncture using a computer generated randomisation schedule, stratified by practitioner and blocked randomised. She will inform the practitioner of group allocation by SMS or fax, depending on the practitioner’s preference. The group allocation will be indicated only by the point prescription to avoid unblinding should the participant inadvertently see the fax or SMS.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation sequence will be computer-generated
