      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: Randomization is based on permutation blocks. Accordingly, 21 blocks are allocated to patients, in each block 2 from the treatment group and 2 from the B treatment group are placed. Eventually, after completion of the blocks, after blocks are completed, group A is treated with metformin 1000 mg tablets, and group B is treated with placebo tablets, Blinding description: Each person in the study will be assigned codes A and B, and the researcher will only be known of the type of group. The outcome evaluator and participants are unaware of the groups. It should be noted that metformin and placebo are similar in appearance, color, and packaging.</study_design>
