Large tumor thrombus extending into the right atrium through the inferior vena cava due to hepatocellular carcinoma: A case report.
Article in Radiology case reports, 2025. 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
This is a case report of a 54-year-old patient with hepatocellular cancer under palliative chemotherapy who admitted with dyspnea on minimal exertion and peripheral oedema over the past 5 days. Echocardiogram revealed a large echogenic mass in the right atrial cavity which did not enhance with intravenous echo contrast agent, and a distended inferior vena cava (IVC) which was occluded by echogenic material with no signs of flow. To distinguish with accuracy if the thrombus was a bland or tumor thrombus, contrast-enhanced Computed Tomography (CT) was performed. CT Pulmonary Angiography and abdominal contrast-enhanced CT showed a distended and occluded IVC by a mass that extended to the right atrium and enhanced with intravenous contrast agent, and thus the mass was considered as a tumor thrombus. Due to the impaired performance status and liver function of the patient, supportive treatment was preferred instead of a surgical or radiological intervention. Large tumor thrombus extending into the right atrium through the inferior vena cava due to hepatocellular carcinoma has a rare incidence and is associated with a poor prognosis.
