      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: Individuals are divided into two groups of intervention and control by simple randomization by a table of random numbers. In order to hide random allocation, the method of sealed envelopes is used, in which the type of treatment for each patient is written as even or odd numbers on a piece of paper and is placed in a sealed envelope. After the visit, an envelope is randomly removed for each patient. Doctors and patients do not know the type of treatment, Blinding description: This is a double blind study. Physician take an envelope, respectively which is blind to the patient's assigned group. According to the assigned number (odd or even numbers), the relevant drug of its therapeutic line is given to the patient. The researcher records the delivered drug code. Patients are also unaware of their treatment group. After completion of the treatment and collecting the data, the analyzer analyzes the data based on their code (odd or even). Evaluators and analyzer will be unaware of the intervention and control groups.</study_design>
