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
Blood flow abnormalities in occluded or narrowed vessels limit drug delivery and contribute to recurrent vascular disease. Existing endovascular or pharmacological approaches do not directly address impaired local flow. Here we propose a miniature endovascular soft robot for active blood flow regulation and enhanced fluid exchange and drug transport in occluded vessels. The soft robot integrates a magnetic body for navigation with cilia that generate metachronal waves to drive the flow. Navigation and flow regulation are decoupled, allowing positioning at target sites followed by local flow enhancement. We investigate the flow regulation mechanism and optimize the structural parameters of the cilia carpet. We validate flow regulation in different vessel phantoms with biologically relevant conditions and in large animal studies. The system restores flow in occluded branches and improves delivery of therapeutic agents, accelerating clot dissolution with reduced residual obstruction and shorter recanalization time both in vitro and in vivo. This technology allows the local modulation of vascular flow, supporting more effective and controlled endovascular therapies.
