      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Prevention, Randomization description: The sample size is 112 , with 56 people in each group. Block randomization method was designed by the group's epidemiologist using Stata version 13 software. The size of blocks considered is 6, Blinding description: The random allocation list for patients is solely available to the epidemiologist. To hide the random allocation process, 112 card sequences of treatments will be written accordingly, and then the cards will be placed inside sealed envelopes. On each 10-digit random code packet, the order is written and the framework is written that the patient identification number is relevant and the methodologist will simply be aware of the design of the code. When the physician announces the eligibility of a patient, the methodologist will provide the envelope. The person evaluating the outcomes is a third person who is unaware of the random allocation process and type of treatment. To analyze the data, a statistician who is separate from the study process and who is unaware of all the processes performed will be used.</study_design>
