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

Here, we introduce a new name into the bacterial energy conservation lexicon: facilitated fermentation. This name is necessary because the more familiar terms "respiration" and "fermentation" do not adequately describe how electron balancing is coupled to energy conservation for organisms that engage in this metabolism. Facilitated fermentation is when ATP is predominantly made via a substrate-level pathway that is redox-coupled to a terminal electron acceptor reduced outside of the cell. The coupling is often facilitated by an extracellular electron shuttle or outer membrane protein that shuttles electrons from the electron transport chain to the extracellular acceptor. Naming facilitated fermentation is timely because it has recently been demonstrated to support both growth and non-growth states in bacteria that are important in nature and disease. We hope that the introduction of this term will inspire future research to evaluate the extent of facilitated fermentation's prevalence and impact in the microbial world and beyond.
