Classification of fundic gland polyps for predicting gastric neoplasms in Helicobacter pylori-negative patients with familial adenomatous polyposis.
Article in Gastric cancer : official journal of the International Gastric Cancer Association and the Japanese Gastric Cancer Association, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundIn familial adenomatous polyposis (FAP) patients, fundic gland polyps (FGPs) have been considered a risk factor for gastric neoplasms. We speculated that FGPs in FAP patients spread directionally from the greater to the lesser curvature of the gastric body and investigated the relationship between the distribution of FGPs and gastric neoplasm development.
methodsWe extracted 195 FAP patients from two institutions and reviewed their medical records. Gastric polyposis was classified based on the FGP distribution (P0, no FGPs; P1, localized in the fundus or greater curvature of the gastric body; P2, spreading to the anterior or posterior wall; P3, involving the proximal half of the lesser curvature; and P4, spreading from P3 to the anal side of the lesser curvature).
resultsThe 195 eligible patients were divided into the neoplasm group (n = 54, 28%) and the non-neoplasm group (n = 141, 72%). Overall, 24% of the patients were Helicobacter pylori (H. pylori)-positive. In the FGP distribution, the rate of patients with gastric neoplasm tended to increase significantly with each step towards an increasingly wide distribution from P0 to P4 in H. pylori-negative patients, but not in H. pylori-positive ones. In addition, in H. pylori-negative patients, the likelihood of neoplasm increased consistently from P0 to P4, with the highest odds ratio (95% confidence interval) at P4 of 14.1 (2.5-154.4). Furthermore, multivariate analysis showed P4 and Spigelman stage ≥III were significantly associated with gastric neoplasm development.
conclusionFGP distribution was correlated with gastric neoplasm development in FAP patients.
