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
Self-powered wearable systems for biomechanical energy harvesting and motion monitoring are highly desirable for sports training and rehabilitation. Herein, a hydrogel-based triboelectric nanogenerator is developed by integrating a Poly(vinyl alcohol)-MXene@carbon nanotube-deep eutectic solvent conductive hydrogel electrode into a single-electrode triboelectric configuration. Owing to the flexible conductive network and DES-regulated hydrogel structure, the PC-TENG delivers an open-circuit voltage of 82.7 V, a short-circuit current of 10.9 μA, a transferred charge of 28.1 nC, and a maximum output power of 129.9 μW. The device also shows stable output under varying humidity, temperature, and prolonged operation. As a proof-of-concept application, the PC-TENG is integrated into a wearable self-powered sensing system for sports-motion monitoring, demonstrating distinguishable motion-related signal responses and the potential for posture monitoring and biomechanical feedback. This work provides a promising strategy for hydrogel-enabled triboelectric wearable systems with balanced output performance, environmental adaptability, and application potential in intelligent sports monitoring.
