Malignant Extra-adrenal Paraganglioma of the Bladder: A Rare Clinical Entity.
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
Bladder paragangliomas are uncommon extra-adrenal neuroendocrine tumors that arise from chromaffin tissue within the bladder wall. Clinical presentation varies from hematuria to catecholamine-related paroxysms, and malignant transformation, although uncommon, carries significant morbidity. We report a 45-year-old woman who presented with painless hematuria. Contrast-enhanced computed tomography (CECT) revealed a 3.6×3 cm lobulated, enhancing posterior bladder wall mass. Transurethral resection of the bladder tumor (TURBT) was performed, and histopathology confirmed paraganglioma. The patient was asymptomatic for six months, when she re-presented with recurrent hematuria and palpitations. Urinary normetanephrines were markedly elevated (3239 μg/24 h; normal 119-451 μg/24 h).
