A Case of a Grade 3 Gallbladder Neuroendocrine Tumor With Rapid Recurrence After Curative Resection.
Article in Cureus, 2023. 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
Primary gallbladder neuroendocrine tumor (GB-NET) is extremely rare. Therefore, tumor behavior and adequate treatment in GB-NETs are still unclear. A 74-year-old man without any specific complaints was referred to our hospital cause of gallbladder tumor. Abdominal ultrasonography examination revealed a 22-mm non-pedunculated tumor in the gallbladder body. Contrast-enhanced computed tomography showed a polyp that was enhanced in the arterial phase. The patient underwent gallbladder bed resection and radical lymphadenectomy with a diagnosis of gallbladder carcinoma. Macroscopically, the resected specimen showed a nodular expanding tumor measuring 32×15 mm in the gallbladder body. From the pathological findings, a grade 3 GB-NET was diagnosed. Only cystic lymph node metastasis was observed. The patient was discharged uneventfully, but bone and lymph node metastasis were detected eight months after surgery. We conclude that grade 3 GB-NET shows occasionally malignant biological behavior although NET G3 is distinguished from neuroendocrine carcinoma in the current WHO 2019 classification of NET.
