Protocol summary

Study aim
Comparison of probiotic yogurt and ordinary yogurt consumption on serum Pentraxin 3, N-terminal prohormone of brain natriuretic peptide, Apo B100, oxidized low density lipoprotein, ADMA, lecithin Cholesterol acyl transferase activity, sCD163 to sTWEAK ration and urea nitrogen in patients with chronic heart failure

Randomization (investigator's opinion)
Randomized
Randomization description
For randomization, the permuted block randomization will be used with quadruple blocks. According to the sample size of 90 , 23 blocks will be produced using the online site (www.sealedenvelope.com).
Blinding (investigator's opinion)
Double blinded
Blinding description
In order to apply concealment in the randomization process, unique codes will be used on yogurt containers, the code being generated by the software. By entering each individual into a study based on the produced sequence , the yogurt container in which the code is registered will be assigned to the individual.During the research, the random list is provided to the statistic consultant, and the participants, the project implementer and all those who participate in the measurement of the indicators will not be aware of the assigned groups.
