Toxic effects of seu are different from those of other staphylococcal enterotoxins.

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
background/purposeStaphylococcal enterotoxins (SEs) are soluble extracellular proteins excreted by Staphylococcal bacterial strains, sharing similar structures and virulence. More than 20 genotypes of SEs have been identified, but the toxicity of some new SEs is still unclear.
methodsIn this study, we assessed the toxicity effects of six recombinant SEs (rSEA, rSEO, rSEG, rSEK, rSEU and rSEQ) on Balb/c mice by reverse transcription-polymerase chain reaction (RT-PCR)-based methods and enzyme activity detection.
resultsExcept rSEU, the other five SEs resulted in systemic inflammatory responses with a significant increase of spleen and liver index and decrease of thymus index. SEs enhanced the enzyme activities of liver POD, T-SOD, LDH but reduced the activity of liver GSH-PX. The transcription levels of five cytokines were all down-regulated by rSEA, rSEG and rSEQ at a dose of 20 ng/g, which was coincided with the results of Caspase 3 level. The transcription and expression of IFN-γ, IL-4, IL-6, and TNF-α involved in inflammatory response were significantly up-regulated by rSEs at a low dose (20 ng/mL) except rSEU
conclusionOur results reveals that the rSEA, rSEO, rSEG, rSEK, and rSEQ have cytotoxicity and superantigenicity for Balb/c mice except the rSEU enterotoxin.
