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

Volatile fatty acid (VFA) accumulation is a common issue that compromises the performance of biological hydrogen methanation systems (BHMs). This accumulation is often triggered by fluctuations in hydrogen supply, which can disrupt microbial activity and lead to system instability. To address this challenge, this study investigated the impact of employing a microbial electrolysis cell (MEC) in BHMs to mitigate system instability and acid build-up. As such, a conventional anaerobic digester (AD) and a microbial electrolysis cell, both supplemented with exogenous hydrogen, were evaluated for their performance in hydrogen methanation. The effect of exogenous hydrogen at high addition rates (> 4:1 CO
