Persistent fecal occult blood due to the small intestinal metastasis of pleomorphic lung carcinoma.
Article in Journal of surgical case reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
The gastrointestinal tract is one of the locations that lung cancers cause metastasis. A 70-year-old male underwent right lower lobectomy while presenting fecal occult blood with a preoperative colonoscopy showing colon polyps as the cause. The pathological diagnosis was pleomorphic carcinoma of the lung, with stage pT3N0M0. Seven months after the lung surgery, the patient presented with sudden-onset abdominal pain and severe anemia. Computed tomography scanning revealed a large mass in the abdominal cavity, and subsequent intestinal endoscopy demonstrated jejunum tumors. Partial jejunum resection was successfully performed. The patient developed multiple peritoneal nodules suggesting metastatic tumors but well responded to an immune checkpoint inhibitor. It can be challenging to diagnose gastrointestinal metastasis in routine radiography; therefore, endoscopic examination, including the small intestine, might be an important option when a lung cancer patient with advanced clinical stage presents with abdominal symptoms, including fecal occult blood.
