Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients are screened for eligibility by a reaserach assistant. After informed consent is obtained, study medication is prepared in pharmacy. Study group allocation is done using sealed serially numbered opaque envelopes based on the randomization schedule.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization is performed using a computer-generated randomization schedule
Masking / blinding
Blinded (masking used)
