From compost to clean energy: influence of cathode potential evolution on hydrogen production in bioelectrochemical reactors.
Article in Bioprocess and biosystems engineering, 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
Microbial bioelectrochemical technologies rely on the development of biofilms on electrode surfaces; therefore, a high surface area in packed anodes is advantageous for their performance. In addition, bioelectrochemical reactors (BERs) for hydrogen production require low-cost installation materials to enable large-scale implementation. In this study, a one-liter BER was constructed using 0.38 L of carbon felt as a packed bioanode, 0.65 L of compost leachate as the electrolyte, and a stainless-steel mesh cathode. The reactor was operated under an anode potential of 0.05 V vs. Ag/AgCl (KCl, 3.5 M) in batch cycles of 24 h each. After medium replacement, the maximum accumulated gas volume reached 2.37 L, corresponding to a production rate of 7.38 m⁻
