2 Cases of Large Cystic-Solid Perivascular Epithelioid Cell Tumor: Case Report and Literature Review.
Article in Hepatic medicine : evidence and research, 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
Perivascular epithelioid cell tumors (PEComas) are rare mesenchymal tumors that tend to occur in multiple organs and the biological behavior of it between benign and malignant. They are even less common in the liver and there is still no effective treatment method established. In particular, how to deal with it when the imaging manifestations of the lesion are predominantly giant cystic are a question that we need to investigate. We present PEComas in two female patients with large cystic-solid lesions on ultrasound with clinical signs of nonspecific pain and a large mass in the right upper quadrant. Both patients underwent contrast-enhanced ultrasound (CEUS) and interventional ultrasound to assist in diagnosis and treatment. Depending on the patient's condition, we take a different approach to treatment. To our knowledge, such reports have never been documented before.
