Magnetic resonance imaging and clinicopathological findings of primary hepatic angiosarcoma.
Article in Abdominal radiology (New York), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeTo investigate the magnetic resonance imaging (MRI) and clinicopathological features of primary hepatic angiosarcoma (PHA) and enhance preoperative diagnosis.
methodsMRI and clinicopathological information of 12 cases proved PHA were reviewed. Summarize the MRI characteristics of PHA combined with literature reviews.
resultsAmong 12 cases (6 males and 6 females; age range, 23-70 years; mean, 53.3 years), one presented as a large mass, two as a diffuse infiltrating tumor, and nine as a mixed pattern of large masses with multiple nodules, all involving both lobes of the liver and ranging from 0.1 cm to 11 cm in diameter. A total of 63 lesions were analyzed, including 21 masses and 42 nodules. 13 masses (61.9%) demonstrated intratumoral hemorrhage. 18 masses (85.7%) demonstrated heterogeneous patchy, ring-shaped, septate, or irregular shaped enhancing foci on late arterial phase (LAP). On dynamic contrast-enhanced MRI (DCE-MRI), 14 masses (66.7%) showed a centripetal or centrifugal pattern of incomplete progressive enhancement. 6 nodules (14.3%) appeared intratumoral hemorrhage. 31 nodules (73.8%) showed no enhancing foci on LAP images and 27 nodules (64.3%) showed enhancement pattern of complete filling, either centripetal or centrifugal pattern. Moreover, 12 cases (100%) exhibited prominent vessels within or adjacent to at least one lesion.
conclusionPHA exhibits diverse appearances on MRI. Typical MRI signs include multifoci with intratumoral hemorrhage, prominent vessels within or adjacent to the foci, as well as varied degrees of progressive enhancement with incomplete filling in dominant masses of PHA.
