When Portal Hypertension Conceals a Gastric Neuroendocrine Tumor: A Rare Mimic of Decompensated Chronic Liver Disease.
Article in Cureus, 2026. 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
Gastric neuroendocrine tumors (gNETs) are uncommon neoplasms arising from enterochromaffin-like (ECL) cells of the gastric mucosa and account for less than 2% of all gastric malignancies.Their clinical presentation varies widely, ranging from incidental indolent polyps to aggressive, disseminated disease. Presentation with portal hypertensive ascites closely mimicking decompensated chronic liver disease (CLD) is exceptionally rare. A 63-year-old postmenopausal woman presented with six months of progressive abdominal distension and was initially evaluated as having decompensated CLD based on a high serum-ascites albumin gradient (SAAG) in ascites. Upper gastrointestinal endoscopy demonstrated a proliferative polypoidal lesion along the lesser curvature of the stomach with high-grade oesophageal varices. Triphasic computed tomography (TPCT) revealed multiple arterially hyperenhancing gastric lesions, retroperitoneal lymphadenopathy, hepatic and splenic deposits, and spleno-portal axis thrombosis, highly suggestive of a gastric neuroendocrine tumor, subsequently confirmed on image-guided biopsy. The patient received therapeutic paracentesis, portal hypertension-directed therapy, nutritional rehabilitation, and geriatric-focused multidisciplinary care. Surgery was deferred in view of comorbidities and functional status; endoscopic surveillance was selected as the preferred management strategy. This case highlights the diagnostic challenge posed by gNETs masquerading as decompensated CLD and underscores the need to consider occult malignancy in elderly patients with unexplained high-SAAG ascites lacking established liver disease risk factors.
