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

Due to the intermittency of solar and wind energy generation, efficient energy storage solutions are essential to ensure a global transition to renewable energy sources. Bioelectrochemical Power-to-Hydrogen systems are a promising storage pathway, yet their development is limited by high costs and low productivity compared to conventional hydrogen production. Novel, sustainable, and cost-effective materials, such as carbon-based electrodes, can help to overcome these challenges. This study evaluates five cathodes for hydrogen and methane production in microbial electrolysis cells (MECs) operated at 600 and 800 mV: stainless steel mesh (SSM), two custom-made biochars derived from olive mill waste (OMW-1, OMW-2), and two commercial carbon-based materials (Carbon Black and Black Pearls). OMW-1 achieved a H
