In this study, we will use the block randomization method, and in this two-group clinical trial, we will have four blocks. For each person who enters the study, a code is obtained from the software, and it is determined which group it belongs to (intervention or control).
The work tool is random allocation software, which, in addition to simple randomization, is capable of generating random sequences using the block method. In order to conceal, we use allocation concealment. This method is such that before the allocation of the individual, the allocated group is not known. In this way, we use non-transparent envelopes sealed with a random sequence. In this method, each of the random sequences created is recorded on a card, and the cards are placed in the envelopes in order. In order to maintain the random sequence, the outer surfaces of the envelopes are numbered in the same order. Finally, the lids of the envelopes are glued and placed in a box. Blocking and preparation of envelopes is done by a person not involved in data sampling and analysis; in this way, the person who collects, the person who analyzes, and the participant are informed of the type of intervention received and what group each person belongs to. He has no information.
