This method first uses a random number table, which is a set of numbers that have no pattern or order and which is completely generated. The researcher divides these numbers randomly between the intervention and placebo groups. With the presence of clients, the researcher begins to read the numbers in the specified order. Each client receives its own number and is randomly assigned to either the intervention or the placebo group, Blinding description: This study is a double-blind study. Given that the researcher and patient should not be aware of the contents of the capsules, the third person places the placebo and spirulina into identical and similar capsules and containers and encodes them randomly.
