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

backgroundThe aim of this study was to characterize pathological lesions of the esophageal epithelial tight junction (TJ) complex in a rat reflux esophagitis (RE) model in a search for a reliable diagnostic indicator.

methodsRats underwent an operation to induce RE, with or without rabeprazole treatment (1.0 and 10.0 mg/kg/day). Sham-operated rats served as a control. Fourteen days after the operation, esophagi were isolated from the rats and submitted to double-label confocal immunofluorescence microscopy, and biochemical analyses.

resultsImmunofluorescence microscopy revealed that claudins-1, -3, and -4 were located on the surfaces of epithelial cells in the normal esophagus of the control group, although there were differences in the distribution patterns between claudin-3 and claudins-1 and -4 in the epithelial layer. However, in RE, the immunoreactivity of claudin-3 on the cell surface was decreased, and it appeared instead as a faint granular pattern within the epithelial cytoplasm. Claudin-3 expression in the entire esophageal epithelium was also decreased. The expression and location of claudins-1 and -4 in epithelial cells were basically unaffected in RE. Gastric acid-induced dissociation of claudin-3 elicited instability of the epithelial TJ complex, which was confirmed by sedimentation analysis using centrifugation in a sucrose density gradient. Rabeprazole (10.0 mg/kg/day) attenuated these alterations.

conclusionsOur data indicate that the dispersion of claudin-3 from esophageal epithelial plasma membranes to cytoplasm and the resulting instability of the TJ complex could be one of the most specific and sensitive indicators for monitoring inflammatory and recovery processes in RE.
