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

unlabelledThe gingival epithelium plays a key role in protecting the supporting structures of the teeth from bacteria and their products. In ex vivo experiments, we recently showed that the cytolethal distending toxin (Cdt) from the periodontal pathogen Aggregatibacter actinomycetemcomitans causes extensive damage to gingival tissue. Morphological changes included detachment of the keratinized outer layer, distention of spinous and basal cells in the oral epithelium, disruption of rete pegs, and apparent dissolution of cell junctions. Adherens junctions (zonula adherens) are essential for maintaining barrier function and integrity of gingival epithelium. Therefore, immunohistochemical and RT-PCR analyses of human gingival explants (HGX) and human gingival epithelial cells (HGEC) were utilized for a closer examination of the effects of the Cdt on E-cadherin, the key membrane component of adherens junctions. Although there was some variability among tissue donors, exposure of gingival tissue or isolated epithelial cells to the toxin generally resulted in a pronounced increase in the expression and cytosolic distribution of E-cadherin, accompanied by an increase in levels of the intracellular scaffolding proteins β-catenin and β-actin. These results indicate that the Cdt induced substantial remodeling of adherens junctions, with a potential impact on the barrier function of gingival epithelium. ABBREVIATIONS: cytolethal distending toxin (Cdt), 4',6-diamidino-2-phenylindole (DAPI), human gingival epithelial cells (HGEC), human gingival explants (HGX), human gingival fibroblasts (HGF), transepithelial resistance (TER).
