1 · What the graph read from it

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.

2 · The registry

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 bio-sensors using organic electrochemical transistors (OECTs) powered by flexible organic solar cells (OSCs) show promise for electrophysiological monitoring. However, single OECT bio-sensors face unstable outputs due to the limitations of OSCs under low-light conditions and poor energy autonomy. Here, we show a low-power self-powered physiological sensor employing a dual-OECTs configuration, connected in series and powered by the optimized OSCs, which shows more stable signal output and faster response compared to single OECT bio-sensors. Our devices employ the efficient and more stable OSCs to power amplifier by suppressing charge recombination and improving flexibility, thereby facilitating long-term, on-demand use. This integrated device can be attached to human-skin to stably monitor signals, including electrocardiograms, electromyograms and electrooculograms across a wide range of illumination intensities (500 lux-50,000 lux). The design offers a simple architecture for wearable low-power self-powered bio-sensors without external energy supplies/storage, highlighting their potential in real-time disease diagnosis and prevention scenarios.
