Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The active and placebo treatments were assigned to identical containers numbered 1-40.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Corresponding numbered slips of paper were drawn randomly from an envelope to assign patients after screening. This was done by the study co-ordinator. The envelope was kept in a secure location throughout the randomisation process.
Masking / blinding
Blinded (masking used)
