For this purpose, 10 blocks of 8 members with different sequences, but equal proportions are composed of two groups A and B and are numbered from 1 to 10. With the RANDBETWEEN function, 10 random number between 1 and 10 is specified, the corresponding blocks of these numbers are placed in a row, and a random chain of groups A and B is formed. Group A is selected as the intervention group and group B as the control group. In order to conceal the random allocation, 80 envelopes with aluminum wrappers (in order to obscure the contents of the envelopes) will be prepared and the letters A and B will be recorded on the cards and the cards will be placed in the envelopes in a random chain. Finally, by entering the study, patients will open the envelopes in order and their assigned group will be revealed, Blinding description: In this study, both of patients and researcher are blinded. Placebo is prepared the same as the drug capsule. Drug and placebo are coded into A and B by the third supervisor and randomized by block randomization method. N/A Dyslipidemia.
