Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The details of the series are kept in a set of sealed envelopes, each bearing only the case number on the outside. After admitting into the operating room and just before the induction of anaesthesia, the numbered envelope was opened and the card inside determined which group the patient would be affiliated to.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization into one of the four groups was based on Excel random-number generation.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
