The size of the blocks is 4 and 6. Randomization will be done individually. In the Block Method, due to the use of different combinations in each block, it is not possible to predict the randomization sequence, so the concealment process will also be observed. For the guaranteed encryption process, the randomization files are generated in Excel and will remain close to the epidemiologist's colleague, then the Epidemiologist will be contacted to allocate the eligible people to two groups, the sick person, and to position each person in the groups, will be decided according to the randomization sequence. The online program available on the Sealed Envelope website will be used to generate the block randomization sequence.
