Case Report: Feline adrenal pheochromocytoma with a synaptophysin-positive, chromogranin A-negative immunophenotype.

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
Pheochromocytoma is a rare adrenal medullary neoplasm in cats, with limited published cases and diagnostic challenges due to variable clinical presentation. An 8-year-old neutered male domestic shorthair cat presented with severe watery diarrhea, lethargy, and anorexia. Diagnostic evaluation revealed chronic kidney disease, pyelonephritis, and a large cystic right adrenal mass identified on ultrasonography and computed tomography. Endocrine testing did not support hyperadrenocorticism or hyperaldosteronism, and functional assessment of catecholamine excess was not performed. Surgical adrenalectomy was elected due to mass size and rupture risk. Histopathological examination demonstrated a medullary adrenal neoplasm composed of polygonal cells arranged in characteristic packets. Immunohistochemistry revealed synaptophysin positivity with negative chromogranin A staining, supporting a diagnosis of pheochromocytoma. Postoperative recovery was uneventful, and the cat remained normotensive and clinically stable at one year, with chronic kidney disease managed medically. This case underscores the diagnostic complexity of feline pheochromocytoma and highlights the importance of integrating imaging, histopathology, and immunohistochemistry, as chromogranin A negativity does not exclude this diagnosis.
