Relationship between gastric mucosal atrophy, cystic dilatation, and histopathological characteristics.
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
objectiveThis study aims to elucidate the relationship between gastric mucosal atrophy, cystic dilatation, and their associated histopathological characteristics.
methodsA comprehensive analysis was conducted on endoscopic biopsy specimens from 527 cases exhibiting gastric mucosal cystic dilatation. Detailed histological observations and immunohistochemical analysis were performed.
resultsThis study included 527 endoscopic biopsy and ESD samples, with a male predominance of 313 cases (59.4%) and 214 female cases (40.6%). The age distribution was as follows: 207 cases (39.3%) were ≤ 60 years, while 320 cases (60.7%) were > 60 years. Regarding cystic dilatation types, 287 cases (54.5%) were identified as simple cystic dilatation, and 240 cases (45.5%) were classified as compound cystic dilatation. Gastric mucosal atrophy was observed in all cases of cystic dilatation, with the atrophic process initially disrupting the structural integrity of the gastric glands. This led to increased interstitial tissue and widening of glandular septa, followed by compensatory hyperplasia and cystic cavity formation. Simple cystic dilatation (54.5%) and compound cystic dilatation (45.5%) were distinguished based on the extent of cellular and structural changes. Simple cystic dilatation could progress to early gastric cancer, presenting as gastric papillary cystadenocarcinoma, while compound cystic dilatation could lead to tubular papillary adenocarcinoma. The progression from simple to complex lesions involved low- and high-grade intraepithelial neoplasia, ultimately resulting in mixed cystadenocarcinoma-glandular tube papillary carcinoma, indicative of early-stage gastric cancer.
conclusionThe classification, grading, and histopathological characteristics of cystic dilatation in the gastric mucosa are crucial for guiding clinicians in precise treatment and vigilant monitoring of malignant transformation. This approach is significant for the prevention and control of gastric cancer progression.
