      <study_design>Randomization: Randomized, Blinding: Triple blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: Randomization method and description: Balanced block randomization.
Unit of randomization: Individual participant.
Stratification layers (if stratified randomization is used): Not applicable.
Randomization tool: The sequence of drug and placebo allocation is determined using statistical software and predefined block sizes.
Random sequence generation: Drug and placebo packages are identical in appearance and labeled with sequential numbers according to the randomization list. These are provided to the designated unit/person responsible for dispensing the intervention, to be distributed in order to participants enrolled in the study.
Allocation concealment: The randomization list is prepared in duplicate and kept by an individual not involved in the study and not present at the study site. During data analysis, only two groups labeled A and B are provided to the analyst. The identity of the drug and placebo groups is revealed only after completion of the analysis and summary of results, Blinding description: Since the placebo in this study is manufactured and provided by the producing company, there is no visual difference between what is given to the dispenser and the patient. Therefore, there is no way for the outcome assessor, data analyst, or even members of the safety and data monitoring committee to identify the type of intervention. All parties remain blinded to whether the patient receives the active drug or the placebo.</study_design>
