Calvarial metastasis from malignant pheochromocytoma associated with multiple endocrine neoplasia.
Article in Surgical neurology international, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
Background: Malignant pheochromocytoma is a rare neuroendocrine tumor that may metastasize to the bones, liver, lungs, kidneys, and lymph nodes. Cerebral and skull metastases are even rarer, with only 17 cases reported in the literature. To the best of the authors' knowledge, this is the first reported case of a purely calvarial metastasis from malignant pheochromocytoma associated with multiple endocrine neoplasia type 2A (MEN2A). Case Description: A 31-year-old Filipino man diagnosed with MEN2A was found to have elevated urine metanephrine on routine surveillance, and workup revealed right adrenal and hepatic masses and a focus of intense tracer accumulation on the right frontal bone on metaiodobenzylguanidine I-123 scan. All the newly discovered lesions were resected to achieve tumor control. Histopathology revealed a diagnosis of pheochromocytoma for the calvarial lesion. Conclusion: Malignant pheochromocytoma may give rise to indolent metastatic foci that can easily be missed without a thorough examination. Misdiagnosis and delays in management of this disease can be detrimental, resulting in irreversible complications and death.
