From the type of drug label and placebo until the end of data analysis, the researcher, patient and analyst will not know and this position will remain confidential.
Method of assigning letters A and B to patients randomly:
Patients who refer to shariati Hospital for treatment of rheumatoid arthritis and are eligible for the study are based on a randomized list, which randomly divides the numbers 1 to 86 using SPSS software in letters A and B (each 43 items) will receive a medicine or placebo with the appropriate label.
-
Blinding (investigator's opinion)
-
Double blinded
-
Blinding description
-
purslane or placebo is coded by a third person who does not know the contents of the packages. Upon each person entering the study, based on the generated sequence, a packages containing the powder in which the code is recorded will be assigned to the person. None of the participants as well as the researcher and analyst will know the assigned groups. The packages are prepared by the company and placebo and purslane packages are similar in terms of internal and external appearance.
