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.
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
To develop an animal model for Indian strain Helicobacter pylori (H. pylori) infection. This model will allow one to study many facts of H. pylori infection in a more controlled manner. Mongolian gerbils were orogastric inoculated with two different Indian strains of H. pylori at different time points. Animals were sacrificed and looked for the presence of infection up to 52 weeks post-inoculation using a variety of techniques. Simultaneously, serums from these animals were also tested for antibody, and changes in the histopathology of stomach on H&E (hematoxylin and eosin) stains were also noted. Experimental sets of Mongolian gerbils were orally fed two strains of H. pylori obtained from human case by culture of different cagA and vacA strains three times daily on days 0, 2, and 4. H. pylori ATCC26695 strain was used for antisera preparation; three animals from each group were sacrificed at different time periods 2, 4, 8, 12, 26, 38 and 52 weeks after infection along with one control animal. Infections with H. pylori were confirmed in all the animals from 4 weeks onwards up to 52 weeks with histopathological changes in conformity with H. pylori gastritis. Wild Mongolian gerbils can be infected with Indian strains of H. pylori, and the infection persists at least 1 year. However, intensity of gastritis was milder than that seen in human case.
