The number of samples assigned to each study groups become equal and in this study, we will have blocks of size 4. Random allocation software is used that this random sequence generation software in addition to simple randomization are able to generate random sequence by blocking method. Allocation concealment is also used, which is the method used to execute a random sequence on study participants. In such a way that the assigned group is not known before the individual is assigned. Using Sequentially numbered, sealed, opaque envelopes, each random sequence created is recorded on a card. And the cards are placed in the envelopes respectively. In order to maintain a random sequence, the envelopes are numbered in the same way on the outer surface. Finally, the lids of the envelopes are glued and placed inside a box, respectively. At the beginning of the registration of participants, based on the order of entry of eligible participants into the study, one of the envelopes is opened in order and the assigned group of the participant is revealed, Blinding description: Evaluator and statistical analysts are blind to the research process.
