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
Wearable sensors for swimming safety monitoring have attracted growing interest due to the need for real-time and reliable tracking in aquatic environments. Here, we present a single-wire triboelectric nanogenerator (SW-TENG) integrated into a life jacket for self-powered swimming safety monitoring. The SW-TENG is composed of a large silicone tube coated with copper paint and a smaller silicone tube wrapped around a single wire, forming a flexible structure suitable for underwater operation. The device delivers a peak voltage of 57.2 V, transferred charge of 30.1 nC, and current of 3.5 μA under 25 N load at 2 Hz. When embedded into a swimsuit, it enabled sensitive multi-joint motion tracking and distinguished among various swimming behaviors. With wireless data transmission, the system provides real-time, self-sustained monitoring crucial for swimmer safety and performance evaluation. This work demonstrates the potential of SW-TENG technology for intelligent aquatic safety systems and rapid rescue applications.
