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

Human walking generates renewable and accessible energy with a potential output of up to 67 W. However, effectively harnessing this energy is significantly impeded by the high humidity within the shoe, stemming from both the human body and the surrounding environment. In response to this challenge, we introduce an intrinsically waterproof and biocompatible magnetoelastic smart insole engineered to generate electricity during walking by utilizing the giant magnetoelastic effect. The smart insole features an ultralow internal impedance of ∼80 Ω, a substantial current output up to 59.9 mA, and a peak power output of 1.04 mW, performance characteristics that enable the sustainable powering of running lights as well as provide personalized thermoregulation. Furthermore, the insole demonstrates exceptional durability, consistently maintaining peak performance, even with prolonged use and immersion in water. With these extensive advantages, the smart magnetoelastic insole serves as a sustainable, efficient, and robust power source for the Internet of Things, providing a pervasive, decentralized, and mobile energy solution that overcomes the inherent limitations of traditionally centralized and rigidly structured power grids.
