    Patients who are eligible for inclusion based on the inclusion criteria, randomly using the block randomization method, are divided into two groups based on gender: intervention and placebo. After obtaining the consent of patients for supplementation, the intervention group will be supplemented daily with 15 g of dry powder of Spirulina platensis algae. The placebo used in this study will be similar to the supplement used in the intervention group in terms of shape and smell.
    Based on the entry criteria, patients who are eligible to enter the study are randomly divided into two intervention and control groups using the block randomization method. After obtaining consent from the patients, the intervention group will receive 15/2 g spirulina platensis algae powder daily.

    At the beginning of the patient's hospitalization before the start of the study, demographic information from patients is recorded, information related to the history of specific diseases and related to anthropometrics and current disease conditions. Patients who are eligible for inclusion based on the inclusion criteria, randomly with the block randomization method that will maintain balance in the two groups are placed in two groups of intervention and placebo. Using a random block table for patients makes the randomization action equal in the two groups in total. Also, using a random block table causes patients to be equally assigned to both groups at each stage of the study. These small blocks maintain a balance between the two groups and make the number of people in each group similar. In our study, considering that there are two groups, 4 patients are considered for each block.

Patients who are eligible for inclusion based on the inclusion criteria, randomly with the block randomization method, are placed in two groups of intervention and control. In our study, due to changing the study method from single-blind to open-label, random blocks of variable size will be used to avoid revealing the last allocation in each block.
    در بدو بستری قبل از شروع مطالعه از بيماران اطلاعات دموگرافيک،اطلاعات مربوط به سابقه بيماری های خاص و مربوط به تن سنجی و شرايط بيماری حاضر ثبت می گردد. بيمارانی که واجد شرايط ورود به مطالعه، بر اساس کرايتريای ورود هستند به شکل تصادفی با روش block randomization که موجب حفظ تعادل در دو گروه خواهد شد، در دو گروه مداخله و دارونما قرار می گيرند. بيماران با استفاده از جدول بلوک های تصادفی که نه تنها باعث می شود Randomization در مجموع در دو گروه مساوی باشد، بلکه در هر مرحله از انجام مطالعه نيز بيماران بطور مساوی به هردو گروه تخصيص يابند. اين بلوک های کوچک باعث حفظ تعادل بين دو گروه می شود و تعداد افراد در هر گروه را مشابه هم می سازد. در مطالعه ما با توجه به اينکه دو گروه وجود دارد برای هر بلاک چهار بيمار در نظر گرفته شده است.
    در ابتدای بستری شدن بیمار قبل از شروع مطالعه، اطلاعات دموگرافیک بیمار در مورد سابقه بیماری های خاص و مربوط به آنتروپومتریک و شرایط فعلی بیماری ثبت می شود. بیمارانی که بر اساس معیارهای ورود به مطالعه واجد شرایط ورود هستند، به صورت تصادفی با روش block randomization در دو گروه مداخله و کنترل قرار می گیرند. در مطالعه ما، با توجه به تغییر روش مطالعه از یکسو کور به برچسب باز، از بلوک‌های تصادفی با اندازه متغیر استفاده خواهد شد تا آخرین تخصیص در هر بلوک آشکار نشود.
    The present study is a single-blind clinical trial study so that the patient is unaware of the intervention and the medical staff is aware of the intervention.
    مطالعه حاضر يک مطالعه کارآزمايی بالينی يکسو کور است به طوری که بيمار به مداخله ناآگاه بوده و کادر درمانی آگاه هستند.
