Circadian-Inspired Hydrogel Moisture Electricity Generation.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Energy harvesting from ambient moisture offers a ubiquitous solution to the energy crisis, free from geographical restrictions. While hydrogel-based moisture electric generators (MEGs) show promise as scalable sustainable energy sources, they currently face significant challenges regarding performance degradation due to inevitable water saturation or desiccation. Here, we present a circadian-inspired hydrogel MEG that exhibits sustained electricity generation by leveraging diurnal temperature-moisture fluctuations-traditionally considered detrimental noise-as a critical driving force. By combining an asymmetric hygroscopic hydrogel architecture with a conditioning treatment, the device undergoes reversible internal water redistribution, which is closely associated with periodic reversal of the effective driving force for electrical output. The resulting MEG delivers a short-circuit current density of 75 µA cm
