GidA expression in Salmonella is modulated under certain environmental conditions.
Article in Current microbiology, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Glucose-inhibited division (GidA) protein is widely distributed in nature, and is highly conserved among bacteria and eukarya. In our previous study, a gidA mutant was attenuated in both in vitro and in vivo models of Salmonella infection. Furthermore, deletion of gidA resulted in a marked reduction in the expression of many virulence genes and proteins, suggesting a role for GidA in the regulation of Salmonella virulence. In this study, the effect of different environmental conditions (glucose, EDTA, and pH 5) on GidA expression in Salmonella was examined. Transcriptional analysis using real-time RT-PCR and a β-galactosidase assay, displayed no differences in gidA transcription and promoter activity in different environmental conditions. Conversely, semiquantitative Western blot analysis revealed a significant increase in the GidA expression in Salmonella when grown under different environmental conditions. Salmonella in vitro virulence assays showed an increased virulence potential in the environmental conditions correlating to the increase in GidA expression. Together, our data indicate that GidA expression is modulated under different environmental conditions which correlate to increased Salmonella in vitro virulence.
