Ordered expression of virulence genes in Salmonella enterica serovar typhimurium.
Article in Folia microbiologica, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Using transcriptional promoter fusions, we investigated the expression of selected SPI-1 and SPI-2 genes of Salmonella enterica serovar Typhimurium (S. Typhimurium). Promoters of genes related to the invasion of the epithelial cell (hilA, hilC, hilD, invF, sicA, sopA, sopB and sopE2) were active in Luria-Bertani (LB) medium and LB with butyrate but were suppressed by bile salts and in glucose minimal (M9) medium. Genes related to S. Typhimurium intracellular survival (phoP, ssrA, ssaB, ssaG, sifA, sifB and pipB) were characterized by their expression in stationary phase in LB and M9 medium. Activity of phoP and ssrA promoters indicated that these might be expressed inside the gut. SPI-1 genes were expressed on the transition to stationary phase while SPI-2 genes were expressed in stationary phase. Among SPI-1 genes, those with regulatory functions preceded in expression the effector genes and sop genes were expressed in the order of sopA, sopB and sopE2, showing hierarchy in the expression of S. Typhimurium virulence genes.
