Metastatic pulmonary pleomorphic carcinoma involving the jejunum: a case report and review of the literature.
Article in International journal of clinical and experimental pathology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
We present a case report of a pulmonary pleomorphic carcinoma that metastasized to the jejunum in an 80-year-old woman. The patient was admitted to the hospital with symptomatic anemia and melena that had been ongoing for several months. In 2021, non-small cell carcinoma was diagnosed by fine-needle aspiration. In 2022, a computed tomography (CT) scan revealed an enormous mass in the small bowel. The tumor was resected and showed pleomorphic neoplastic cells with giant and spindle cell morphology. These neoplastic cells were positive for thyroid transcription factor 1 (TTF1). Next-generation sequencing of the secondary tumor revealed 97% genomic similarities to the lung tumor and high expression of programmed cell death ligand 1 (PD-L1). The patient may benefit from immune checkpoint therapy.
