Evaluation of the effect of sweet almond capsule on function of kidney and quality of life in patients with chronic renal failure
Design
Patients with chronic kidney disease, stages 2 and 3, who visited Shahrvand Kidney subspecialty clinic of Sari
Sample size: 60 people
Clinical trial with control group, double-blind, randomized, phase 2 on 60 patients
Randomization: Random Number Table
Settings and conduct
Location: Shahrvand Kidney subspecialty clinic of Sari
For blinding, the patient and attending physician responsible for evaluating patients and also the researcher will be unaware of the type of treatment for each group (drug or placebo). For this purpose, after randomization and division of patients into two groups, the drug and placebo are separated by code A or B, and then they are labled by the statistical consultant. In this way, the patient, the attending physician, and the researcher will not be aware of the type of treatment.
Participants/Inclusion and exclusion criteria
Inclusion criteria: Patients with chronic kidney disease stage 2 and 3, Age range 18 to 65 years
Exclusion criteria: clinically unstable, malignancy, Heart Failure, previous diagnosis of primary hyperoxaluria, History of calcium oxalate kidney stone, Known allergy to almond, Liver failure, Pregnancy, Inability to communicate, Polycystic kidney disease, acute infectious disease
Intervention groups
Intervention group will receive capsules, containing 350 mg of almond, twice a day. Control group will receive placebo capsules exactly according to the original medication, twice a day. Both groups are treated for 8 weeks.

Randomization (investigator's opinion)
Randomized
Randomization description
For randomization, a quadruple block randomization method is used. In this method, all permutations obtained from 2 groups are calculated as follows:
1) AABB 2) ABAB 3) ABBA 4) BABA 5) BAAB 6) BBAA
Among them, using random number table, we will select samples in the following order.
The selected permutation:
3, 1, 4, 5, 2, 6, 3, 1, 2, 5, 6, 4, 1, 6, 3
A is the intervention group and B is the control group. The advantage of this method is that the groups are equal.
Blinding (investigator's opinion)
Double blinded
Blinding description
For blinding, the patient and attending physician responsible for evaluating patients and also the researcher will be unaware of the type of treatment for each group (drug or placebo). For this purpose, after randomization and division of patients into two groups, the drug and placebo are separated by code A or B, and then they are labled by the statistical consultant. In this way, the patient, the attending physician, and the researcher will not be aware of the type of treatment.
Drug and placebo are similar in appearance, color and smell.
