Undifferentiated embryonal sarcoma of the liver masquerading as a cystadenoma in a young adult: a case report.
Article in Journal of medical case reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundUndifferentiated embryonal sarcoma of the liver is an infrequent hepatic malignancy, primarily observed in the pediatric population. This neoplasm is exceedingly rare among adults. Despite its scarcity in adult cases, it remains imperative to accurately discern undifferentiated embryonal sarcoma of the liver utilizing diverse imaging modalities to prevent misdiagnosis with more prevalent benign and malignant hepatic masses. In this case, a comprehensive imaging examination was conducted, encompassing ultrasound, computed tomography, magnetic resonance imaging, and positron emission tomography-computed tomography scans. Notably, the positron emission tomography-computed tomography scan revealed CASE PRESENTATION: This report presents the diagnostic procedure employed for a 37-year-old female patient of Han ethnicity in China diagnosed with undifferentiated embryonal sarcoma of the liver. The patient was admitted with a 2-day history of mid-upper quadrant abdominal pain. The patient's temperature and inflammatory markers, such as white blood cell count and hypersensitive reactive protein, were slightly elevated. Ultrasound showed a cystic-solid nodule in the liver. The computed tomography revealed a cystic mass in the right lobe of the liver, characterized by a low-density shadow and a lack of significant enhancement during contrast-enhanced scanning, initially suggesting cystadenoma. Enhanced magnetic resonance imaging revealed a block-like abnormal signal shadow in the right hepatic lobe, suggestive of various etiologies, including benign lesions, cystadenoma with hemorrhage, or hemangioma with hemorrhage. However, the positron emission tomography-computed tomography showed increased
conclusionOn the basis of this case and a comprehensive literature review, we recommend that clinicians consider the possibility of undifferentiated embryonal sarcoma of the liver in patients presenting with non-specific clinical and serological markers, particularly when there is inconsistency between ultrasound and computed tomography imaging findings, along with elevated
