1 · What the graph read from it

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.

2 · The registry

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

Embryonic stem (ES) cells are susceptible to genetic manipulation and retain the potential to differentiate into diverse cell types, which are factors that make them potentially attractive cells for studying host-pathogen interactions. Murine ES cells were found to be susceptible to invasion by Salmonella enterica serovar Typhimurium and Shigella flexneri and to the formation of attaching and effacing lesions by enteropathogenic Escherichia coli. S. enterica serovar Typhimurium and S. flexneri cell entry was dependent on the Salmonella pathogenicity island 1 and Shigella mxi/spa type III secretion systems, respectively. Microscopy studies indicated that both S. enterica serovar Typhimurium and S. flexneri were located in intracellular niches in ES cells that were similar to the niches occupied in differentiated cells. ES cells were eventually killed following bacterial invasion, but no evidence of activation of classical caspase-associated apoptotic or innate immune pathways was found. To demonstrate the potential of mutant ES cells, we employed an ES cell line defective in cholesterol synthesis and found that the mutant cells were less susceptible to infection by Salmonella and Shigella than the parental ES cells. Thus, we highlighted the practical use of genetically modified ES cells for studying microbe-host interactions.
