For the random allocation of people, it will be done using the minimization method based on gender variables and in the form of balanced blocks. For this purpose, we have 6 pages of paper, on 3 of which the word I, which stands for Intervention, and on 3 of them, the word C, which stands for Control, is written. Then these are placed in a container and randomly extracted from this information box of these people until six pieces of paper are extracted from this package. Again, this operation is repeated until all the sample volume is taken.
Then the participants in the selected blocks will be selected in a balanced way and based on gender according to the predetermined table. To balance the blocks based on sex, two pieces of paper written one of them with the word F, which stands for female, and the other with the word M, which stands for male, are then placed in the compartment and drawn randomly by replacing so that the ratio of women to men is considered to be 2 to 1 in the first block of 6 tuple and 1 to 2 in the next block of 6 tuple until the end, for this purpose the first half of the block of 6 tuple where the ratio of women to men is 2 to 1 If the first two people are randomly selected as men, in order to maintain the ratio of 2 to 1, we will consider the third person as a woman. We will determine the second half of the block based on the first half of the block. In the next block of 6 tuple, this time the ratio is reversed and the ratio of women to men is considered 1 to 2. Again, the lot is drawn by replacing and if the first person is a woman and the second person is a man, the third person is chosen as a woman to maintain the ratio, and this process continues until the end.
The gender variable is considered a potentially confounding variable and the minimization method was used for the least confounding effect in the study.
According to previous similar studies and research objectives, randomization will be done based on gender.
