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
Ultrasound particle image velocimetry (uPIV) has emerged as a widely-used tool for measuring blood flow fields with higher sensitivity and accuracy. However, its clinical application in assessing microvessel-related diseases is hindered by the diffraction limit. While ultrasound localization microscopy achieves super-resolution imaging of deep tissue microvessels, it lacks the capability for rapid imaging of blood flow dynamics. To overcome the challenges in measuring blood flows beyond the diffraction limit, we integrated the strengths of super-resolution ultrasound and uPIV strategies, proposing an approach termed enhanced ultrasound particle image velocimetry (E-uPIV). By the reconstruction of high-resolution microbubble trajectory images and subsequent speckle tracking, E-uPIV accurately maps microvascular structures and dynamically assesses microflow characteristics, eliminating the need of microbubble localization. This approach presents a perspective tool for non-invasively imaging dynamic microflows.
