      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: In the present study, the simple randomization method will be used. The randomization sequence will be determined by the researchers first and then we will proceed to sampling. In this way, we will have 2 pots, in pot number 1 will be numbers from 1 to 63, and in pot number 2, 63, the number of envelopes will be opaque, in which the desired type of treatment is listed. First we will randomly select a number from the first pot and from the second pot we will randomly select an envelope and place them in a designed box. The number from pot number 1 will receive the treatment that came out of pot number 2. We will do this for every 63 issues. In fact, the type of intervention inside each envelope is unclear, which is the randomization concealment method. In fact, the treatment assigned to the numbers is not known until the person comes and the envelope is opened for him, and secondly, the names of the treatments will not be known inside the envelopes, and the names of the treatments will be A, B and C, and only the designer The study will know the type of treatment A and B, C, Blinding description: In this study, the patient and the interventionist or physician are blind and the drug group and placebo are used for blinding. After selecting the samples, the patient and the intervener or physician will have no information about randomization and the allocation process. Physicians are pre-coded (A, B, C) and patients are admitted to the study, respectively.</study_design>
