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

The growing demand for sustainable energy solutions has increased interest in ambient energy harvesters capable of continuous operation under diverse environmental conditions. Here, we report a hygroscopic moisture-electric generator (HMEG) that achieves long-term, self-sustained power generation through an asymmetric architecture composed of montmorillonite and calcium chloride. The integration of hygroscopic materials within a perforated coin-cell structure enables directional moisture transport and persistent ionic gradients, producing a stable open-circuit voltage of 0.55 V and a short-circuit current of 74 µA for 30 days at 50% relative humidity. The device delivers a maximum power density of 3.582 µW cm
