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

Both fungi and bacteria contribute to the efficiency of activated sludge processes. However, fungal degradability has historically been overlooked in the anaerobic fermentation of waste-activated sludge (WAS). This study investigated the role of an enriched microbial consortium of degrading fungi (MCDF) in WAS fermentation. MCDF was initially enriched using a mixture of WAS and two mesophilic anaerobic sludges with chitin as the substrate. Fungal diversity and key cell wall polysaccharides, including chitin, mannan, and glucans, were identified in WAS. The addition of enriched MCDF to WAS significantly increased methane production by 35% and disrupted the floc structure through degradation of native fungi. The enriched MCDF also utilized fungal polysaccharides from four fungal species (
