Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants will be recruited from surgeon's rooms.
Once enrolled, the participant will be randomly assigned to one of two groups. A sealed envelope will be attached to the participant's consent form. This envelope will contain a paper labelled with "knife" or "diathermy", drawn from a box containing an equal number of each (identical from the exterior). The participant will not be informed which group they are assigned to.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
sealed envelope containing label with "knife" or "diathermy", drawn from a box containing equal number of each
Masking / blinding
Blinded (masking used)
