In this study, we will use the Restricted Randomization method of the Blocked Randomization type. Blocking is usually used to balance the number of samples assigned to each of the study groups. This feature helps researchers to ensure that the number of samples assigned to each of the study groups is equal in cases where intermediate analyzes are required during the sampling process.
Randomization tool:
We will use random sequence software (Random allocation software). In addition to simple randomization, these softwares are able to generate random sequences by blocking method.
To hide the Allocation Concealment, we will use opaque sealed, sealed, opaque envelopes. This method is used to perform a random sequence on the study participants. In such a way that the assigned group is not known before the individual is assigned. The random assignment sequence and the list of blocks will be obtained by the statistics consultant with the help of random software. Use 4 blocks to create a random allocation. According to the total number of samples required for the study, which is 68 patients, 34 patients in intervention group (A), 34 patients in control group (B), 17 quadruple blocks including groups A and B are randomly designed through the software. For example, (ABAB), (BABA), (AABB), (BBAA), (BAAB) .... Based on the list of randomly prepared quadruple blocks, a trained person outside the research team is responsible for allocating patients randomly. Obtaining informed written consent, according to the 17 quadruple blocks prepared in the first stage, will be randomly assigned to the intervention group (A) and the control group (B). For example, according to the block (ABAB), each patient enters the intervention, control, intervention and control groups, respectively, after entering the study. This process continues until the last block is selected.
