Intraoperative contrast-enhanced ultrasound features of progressive multifocal leukoencephalopathy: a case report.
Article in Frontiers in neuroimaging, 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
We report the intraoperative ultrasound findings in a male patient with history of stage IVb mantle cell lymphoma who developed new-onset personality changes and gait instability. Brain imaging revealed an extensive right frontal white matter lesion with subtle multifocal spreading. Given the absence of contrast enhancement on MRI and considering the high-dose steroid therapy administered, an open biopsy was performed due to suspicion of cerebral lymphoma. During procedure, intraoperative ultrasound with and without microbubble contrast was carried out, demonstrating distinct echotexture features, determining the site of biopsy. The histological analysis led to a diagnosis of progressive multifocal leukoencephalopathy (PML). To the best of our knowledge, this may represent one of the first descriptions of intraoperative ultrasound characteristics in PML.
