Simultaneous imaging of bidirectional guided waves probes arterial mechanical anisotropy, blood pressure, and stress synchronously.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Arterial biomechanical indicators have long been recognized as fundamental contributors to the physiology and pathology of cardiovascular systems. Probing multiple biomechanical parameters of arteries simultaneously throughout the cardiac cycle is highly important but remains challenging. Here, we report a method to quantify arterial anisotropic stiffness, arterial wall stresses, and local blood pressure in a single measurement. With programmed ultrasound excitation and imaging, arterial axial and circumferential guided waves were simultaneously induced and measured in the longitudinal view. Then, a mechanical model was proposed to quantitatively predict the correlation of arterial guided waves with arterial biomechanical parameters. Our experimental design and biomechanical model enable an elastography method to assess temporal variations in blood pressure, bidirectional stiffness, and mechanical stresses in arterial walls. In vivo experiments were performed on healthy young, normotensive older, and hypertensive older volunteers. The results demonstrate that our method can find applications in understanding aging of cardiovascular system and diagnosis of cardiovascular diseases.
