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

Helicobacter pylori (H. pylori) has become accepted as a human pathogen for the development of gastritis and gastroduodenal ulcer. To develop a simple rat model of chronic H. pylori infection, male Sprague-Dawley rats were pretreated with streptomycin suspended in tap water (5 mg/mL) for 3 d. The rats were inoculated by gavage at 1 mL/rat with H. pylori suspension (5 × 10(8)-5 × 10(10) CFU/mL) twice daily at an interval of 4 h for three consecutive days. Two weeks after inoculation, rats were sacrificed and the stomachs were removed. Antral biopsies were performed for urease test and the stomachs were taken for histopathology. Successful H. pylori inoculation was defined as a positive urease test and histopathology. We reported a 69.8%-83.0% success rate for H. pylori infection using the urease test, and hematoxylin and eosin staining confirmed the results. Histopathological analysis detected bacteria along the mucous lining of the surface epithelium and crypt lumen and demonstrated mild to moderate gastric inflammation in successfully inoculated rats. We developed a simple rat model of chronic H. pylori infection for research into gastric microcirculatory changes and therapy with plant products.
