Clinicopathological characteristics of 30 cases of pyloric gland adenoma: a single center case series.
Article in BMC gastroenterology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo investigate the clinicopathological characteristics of patients with pyloric gland adenoma (PGA), as well as their prognosis.
methodsData of 30 cases from 24 patients, who had been histologically diagnosed as PGA, was retrospectively analyzed. Clinical characteristics, histopathological features, treatment and prognosis were assessed and analyzed.
resultsAmong the 24 patients, there were 15 females and 9 males, with an average age of 59 years old. Ten cases were located in the stomach, 4 in the duodenal bulb and 16 in the gallbladder. The average maximum diameter was 13.5 mm and morphologically the vast majority were type 0-I. The assessment of the background mucosa identified autoimmune gastritis (AIG), Helicobacter Pylori-associated gastritis and familial adenomatous polyposis (FAP) in the stomach, ectopic gastric mucosa in the duodenum and chronic cholecystitis in the gallbladder. Endoscopic resection was performed on the vast majority of gastric and duodenal cases, while all gallbladder PGAs underwent cholecystectomy. Histologically, 33.3% of PGAs showed high-grade dysplasia.
conclusionsDue to malignant potential, it is recommended that PGAs should be completely resected, especially if they are large or show high-grade features. For gastric and duodenal PGAs, endoscopic resection has been proven to be safe and effective. Whether PGAs occurring in the gallbladder and stomach are different tumors still requires more cases for further study.
