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
Recent advances in wearable sensor technologies and functional material engineering have significantly accelerated the development of intelligent sports systems. Here, we developed a rubber tube-structured triboelectric nanogenerator (RT-TENG) that integrates the triboelectric layer, conductive electrode, and mechanical support into a single body, offering simplified fabrication and reduced cost while maintaining reliable output. By employing fluorinated ethylene propylene (FEP) and as the triboelectric pair, the RT-TENG achieves a peak output of 133 V, 27 μA, and 52 nC, with a maximum power of ≈1.0 mW under optimal load. It exhibits strong environmental adaptability with temperature-enhanced and humidity-sensitive performance, as well as force-dependent output and robust energy storage capability. Furthermore, the RT-TENG successfully powers a digital thermo-hygrometer and enables real-time, self-powered monitoring of joint motion and impact intensity in taekwondo, highlighting its promise for wearable biomechanical sensing and low-power sports electronics.
