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

objectiveThe purpose of this study was to elucidate possible mechanisms of fetal neuronal injury in inflammation-induced preterm birth. STUDY

designWith the use of a mouse model of preterm birth, the following primary cultures were prepared from fetal brains: (1) control neurons (CNs), (2) lipopolysaccharide-exposed neurons (LNs), (3) control coculture (CCC) that consisted of neurons and glia, and (4) lipopolysaccharide-exposed coculture (LCC) that consisted of lipopolysaccharide-exposed neurons and glia. CNs and LNs were treated with culture media from CN, LN, CCC, and LCC after 24 hours in vitro. Immunocytochemistry was performed for culture characterization and neuronal morphologic evidence. Quantitative polymerase chain reaction was performed for neuronal differentiation marker, microtubule-associated protein 2, and for cell death mediators, caspases 1, 3, and 9.

resultsLipopolysaccharide exposure in vivo did not influence neuronal or glial content in cocultures but decreased the expression of microtubule-associated protein 2 in LNs. Media from LNs and LCCs induced morphologic changes in control neurons that were comparable with LNs. The neuronal damage caused by in vivo exposure (LNs) could not be reversed by media from control groups.

conclusionLipopolysaccharide-induced preterm birth may be responsible for irreversible neuronal injury.
