Random allocation will be done by Block Randomization method. In this method, we will select eligible people who meet the study entry criteria and then randomly place them in blocks based on age, gender and menopause status. Participants will be divided into intervention and control groups in a ratio of 1:1 by a research assistant who is not involved in the study using random blocks (www.randomization.com). For this purpose, codes A and B will be assigned to intervention and control, and researchers will not know which code is for intervention or control until the end of the study. In the method of using random blocks, we can create blocks and assign codes equally to each block. If we specify two codes in each block (the so-called block size is two), we can make two possible sequences AB and BA. When we randomize the blocks, the same codes can be assigned to each group. If the block size is four, we can make six possible sequences (AABB, ABAB, ABBA, BAAB, BABA, BBAA) and then randomize them. For example, if the block size is two, we can easily know the fact that B comes after A, or if the block size is four, we can predict what the last code will be. This is against the principle of randomization. To solve this problem, the research assistant who performs the randomization has hidden the block size from us and uses randomly mixed block sizes. For example, the block size can be two, four and six.
