Randomization (investigator's opinion)
Randomized
Randomization description
Block randomization with blocks of 4 and 6 will be done using special randomization sites such as sealed envelopes. After specifying the codes, each code is written separately on a sheet. Each sheet is placed in a separate envelope or folded and glued in such a way that it cannot be seen inside (allocation concealment). After obtaining informed consent, a sheet will be removed from each qualified patient and according to the code written in it, people will be placed in two study groups.
Blinding (investigator's opinion)
Triple blinded
Blinding description
The patient receives the drug (intervention or control group) in sealed envelopes that are coded. Coding is done by one of the collaborators of the project and the patient, researcher and analyst are blinded.
