Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects for the study will be recruited from/by:
1. surgeon in his rooms
2. from the operating list
3. by phone call during the week prior to surgery
4. by Participant Information Sheet mailed during the week prior to surgery
Allocation of treatment will be made by randomised number generator to assign the patient to one of the 2 groups. The allocation is concealed in sealed opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
