Assay of Blood and Synovial Fluid of Patients With Rheumatoid Arthritis for Staphylococcus aureus Enterotoxin D: Absence of Bacteria But Presence of Its Toxin.
Article in Jundishapur journal of microbiology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundRheumatoid arthritis (RA) is the most common chronic inflammatory disease. The staphylococcal superantigens are considered as the causative agent of RA disease.
objectivesThis study aimed to assess the presence of staphylococcal enterotoxin D in synovial fluid and blood of patients with RA. PATIENTS AND
methodsA total of 120 blood and SF samples of patients with RA were studied. Bacterial culture, primer pairs design, polymerase chain reaction (PCR), and enzyme-linked immunosorbent assay (ELISA) methods have been used to assess of the staphylococcal enterotoxin D. The data were analyzed through descriptive statistics.
resultsDuring this study and after sequential subcultures, only 5 bacterial strains were isolated. The results of PCR showed the presence of staphylococcal enterotoxin D gene in almost 50% of SF and also in 48.4% of blood samples of patients with RA. Similarly, the ELISA method detected staphylococcal enterotoxin D in 36.16% of SF and in 33.33% of blood of patients with RA.
conclusionsThe result of this study showed that a high percentage of patients with RA have shown staphylococcal enterotoxin D (superantigen D) or entD gene in SF and in blood. However, the origin of this superantigen was not clarified and no Staphylococcus aureus enterotoxin D producer was isolated. This finding indicates other role of this superantigen besides its intoxication. Therefore, staphylococcal enterotoxin D as a biomarker may provide a good model for the diagnosis and treatment of patients with RA.
