Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
After the subject is evaluated by investigators and considered elgible for participation in the study, He/she will be given a Patient information sheet and will be asked to sign an informed concent form if decided to enroll in the study.
Allocation concealment will be carried out through contacting the central pharmacy clinical trial pharmacist who will be holding the allocation schedule.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The block randomisation will be used to generate the sequence to ensure we will get a blanced number of subjects in each study group.
Masking / blinding
Blinded (masking used)
