Article in Journal of ultrasound in medicine : official journal of the American Institute of Ultrasound in Medicine, 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
purposeTo describe a reproducible ultrasound-magnetic resonance imaging (MRI) fusion imaging technique developed for quantitative assessment of carotid wall strain and plaque morphology.
methodsMRI volumes (Oblique T2 Cube) were imported into the Sequoia ultrasound system equipped with an electromagnetic tracking module. The fusion workflow aligned ultrasound and MRI coordinate spaces through anatomical landmark registration of the internal and external carotid arteries. Real-time B-mode and strain imaging were performed with a 10L4 transducer. The fused MRI volume provided spatial context for localization of plaque and intima-media regions. Following alignment, additional B-mode, color Doppler, and radiofrequency (RF) data were acquired on a Siemens S2000/S3000 system to match the imaging plane used during fusion.
resultsThis workflow enabled consistent cross-modality localization of vascular features between MRI and ultrasound, improving repeatability of acquisitions. The S2000 acquisition step ensured that color Doppler and RF data corresponded to the same anatomical orientation defined during fusion.
conclusionThis technique offers a practical framework for ultrasound-MRI fusion in carotid imaging and facilitates direct localization of similar structures across 2 imaging modalities. This approach also enables visualization across different systems with manual visual corroborations that, in this case, enabled standardized RF data collection for quantitative elastography research.
