The random sequence for randomization is block type. This site
It is designed in such a way that there is a limit in the number of groups
There is no random assignment. From block method to volume 4 to create
A random allocation sequence is used. According to the total number of samples
The requirement for the study is 60 patients. 30 patients in the intervention group
A and 30 patients are in group B. There are 15 quadruple blocks including two
Group A and B are randomly designed through the software, for example
Continue on...... (ABAB), (BBAB), (AABB), (ABBA), (BAAB)
Based on the sample size, 60 envelopes 30 envelopes including paper containing A and 30).
An envelope containing B is prepared.Based on the list of blocks
A randomly prepared quadruple, a trained person outside the research team,
He is responsible for randomly assigning patients, after the arrival of each
Patient and hospitalized in the special ward, according to 15 blocks of four prepared in
The first stage of each patient randomly in intervention group A and group B
The samples will be placed and the sample process will be done sequentially
Sampling will be done, the code of each patient to his family member as well
Will allocate data. People in the order of their entry into the study and form
Randomly assigned to the desired group through randomized blocks
Finds. For example, according to the ABAB block, each patient after entering the
study, entered into the intervention, sham, intervention and sham groups, respectively
