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
purposeWith advances in diagnostic imaging techniques of gastric cancer screening with X-ray fluoroscopy, it has been suggested that mucosal projections induced by the vessels distributed in the submucosal layer of the stomach may be mistaken for abnormal mucosal folds. In this study, we aimed to describe the distribution of blood vessels in the submucosal layer of the stomach to improve the diagnostic accuracy of screening of gastric cancer.
methodsTwenty-four stomachs from Japanese cadavers were used in this study. Uncolored or colored contrast agents were injected into arteries and/or veins for macroscopic analyses, X-ray imaging, and methyl salicylate clearing. In addition, histological analysis was performed to examine blood vessels distributed inside the stomach wall.
resultsFollowing contrast agent injection, thick blood vessels were distributed perpendicular to both curvature sides, and branches parallel to both curvature sides flowed from these thick blood vessels, and a vascular network was formed throughout the stomach wall. This vascular network had intra-mural anastomoses connecting both curvature sides. Moreover, in histological analyses, blood vessels depicted by injection were mainly distributed in the submucosal layer.
conclusionThis study strongly suggests that the mucosal projections induced by arteries and veins in the submucosal layer could be mistaken for abnormal mucosal folds. Therefore, a better understanding of the vascular distribution in the submucosal layer is important to improve diagnostic accuracy from imaging studies of the stomach. The information provided by this research may facilitate better accuracy in diagnosis and reduce the number of unnecessary invasive procedures.
