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

Polymorphonuclear leukocyte (PMN) infiltration and migration across colonic intestinal epithelia is a hallmark of inflammation in Shigella flexneri-mediated dysentery. To identify bacterial signals associated with this process, potential stimulatory factors mediating initial PMN association with the epithelium and subsequent transepithelial migration were examined in an in vitro model system. Quantitative analyses revealed that purified S. flexneri lipopolysaccharide (LPS) deposited at the apical surface of polarized intestinal epithelial cells transcytosed to the basolateral pole, a process dependent on the stage of epithelial cell differentiation. Transcytosed LPS in the presence of normal human serum (NHS), a source of LPS binding protein and soluble CD14, mediated both interleukin-8 secretion at the basolateral pole and enhanced PMN adherence. In addition, LPS stimulated a significant degree of directed transepithelial migration of PMNs, an event that was further enhanced in the presence of NHS. These results implicate LPS in signaling subepithelial PMN emigration and enhancing PMN-epithelium interactions prior to and during subsequent Shigella-induced transepithelial migration.
