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
To develop a portable microwave-based detection device integrating hydrogel metasurface technology and machine learning for non-invasive rapid detection of intracerebral hemorrhage. By optimizing electromagnetic wave propagation paths through hydrogel metasurfaces to reduce cranial attenuation of electromagnetic signals and enhance transmission efficiency, combined with machine learning algorithms to analyze complex electromagnetic signatures, the system enables accurate diagnosis of intracerebral hemorrhage. In murine models, the system demonstrated 100% sensitivity, 84.21% specificity, and 93.75% accuracy and an AUC of 0.99 for detecting a 30-μL intracerebral hemorrhage. The incorporation of hydrogel metasurface improved the detection accuracy by 7.8%. This research provides a technical approach for early intracerebral hemorrhage diagnosis, demonstrating advantages including portability, rapid response and high sensitivity. The methodology promises to provide clinically effective early diagnostic solutions for cerebral hemorrhage patients.
