Case report: Synchronous bladder and retroperitoneal paragangliomas: an extremely rare entity.
Article in Frontiers in oncology, 2025. 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
Paragangliomas (PGLs) are rare neuroendocrine tumors originating from chromaffin cells. The synchronous occurrence of bladder and retroperitoneal PGLs is extremely rare. This case highlights the radiological features of dual-site PGLs and their potential for misdiagnosis as bladder cancer with retroperitoneal lymph node metastasis. A 59-year-old female patient was admitted with a 2-week history of abdominal distention. Imaging showed a highly vascularized 1.3 cm × 1.2 cm nodule on the right wall of the bladder and a retroperitoneal mass measuring 1.8 cm × 3.7 cm adjacent to the left side of the abdominal aorta. Postoperative pathological examination confirmed dual-site PGLs. The multifocal appearance and hypervascular characteristics of these tumors may lead to misdiagnosis as bladder cancer with metastasis. Recognizing the clinical, imaging (such as CT and MRI findings), and pathological features is crucial for avoiding misdiagnosis and formulating an appropriate treatment plan.
