      <study_design>Randomization: Randomized, Blinding: Single blinded, Placebo: Not used, Assignment: Parallel, Purpose: Supportive, Randomization description: The randomization is performed using Simple Random Allocation. First, a sequence of random numbers from 1 to 54 is generated using the PASS 2021 software. The software output is a follow-up Excel file containing the numbers from 1 to 54 and a unique code for the study units. The patients who meet the criteria from numbers 1 to 54 are considered and allocated to one of the intervention groups (A, B, or C), Blinding description: To ensure Blinding of the referrals (patients), we use the help of a third person who is unaware of the interventions, and the table is provided to them. When a study unit (patient) is referred and meets the criteria, the intervention group (A, B, or C) is asked from the third person by phone based on the patient's number, and the patient is assigned to one of the specified groups.</study_design>
