Cardiogenic shock due to pheochromocytoma-induced catecholamine crisis in a young woman.
Article in JCEM case reports, 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
A pheochromocytoma is a rare catecholamine-secreting tumor that can cause life-threatening complications. Circulatory shock with a significant cardiogenic component is an uncommon initial presentation. This case describes a previously healthy 30-year-old woman presenting with vomiting, hyperglycemia, and shock. This rapidly progressed to requiring intubation, vasopressor therapy, and resuscitation following cardiac arrest. Imaging revealed a right adrenal mass and plasma metanephrines and normetanephrines were markedly elevated. After stabilization with α- and β-adrenergic blockade, the patient underwent successful adrenalectomy, confirming a pheochromocytoma-induced catecholamine crisis, with full recovery of cardiac function. This case illustrates the diversity of initial presentation of pheochromocytoma, the diagnostic challenges associated with measuring plasma (nor)metanephrines after resuscitation and the reversible nature of catecholamine-induced cardiomyopathy.
