A case of gastric signet-ring cell carcinoma with a long-term retrospective follow-up of 17 years.
Article in Clinical journal of gastroenterology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
A man in his 60s underwent esophagogastroduodenoscopy (EGD) for gastric cancer screening in 2006. A pale, oval, depressed lesion, 8 mm in diameter, was seen in the greater curvature of the gastric antrum. The patient was followed up every 1-2 years. EGD performed 13 years after 2006 showed the lesion with an irregular margin. Histopathological diagnosis of a target biopsy was signet-ring cell carcinoma. The lesion was resected by endoscopic submucosal dissection. The resected specimen was 8 × 3 mm in size, and histopathological examination showed type 0-IIc, signet-ring cell carcinoma, pT1a, Ly0, V0, UL0, pHM0, pVM0. The patient had no history of Helicobacter pylori infection. The serum anti-H. pylori IgG antibody test result and the urea breath test result was negative. Histopathological examination did not reveal the presence of H. pylori. No evidence of atrophic gastritis on endoscopy was found. Based on these findings, the patient was confirmed as not having H. pylori infection. We retrospectively reviewed all previous endoscopic images and confirmed that the lesion was already present in the images taken 17 years ago. To our knowledge, this is the longest retrospective follow-up (17 years) of gastric signet-ring cell carcinoma remaining in the mucosa, without H. pylori infection.
