Enteromorpha prolifera Diet Drives Intestinal Microbiome Composition in Siganus oramin.
Article in Current microbiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Enteromorpha prolifera (E. prolifera) contains complex sulfated polysaccharides that are resistant to biological degradation. Most organisms cannot digest biomass of E. prolifera, except Siganus oramin (S. oramin). This study was conducted to identify the bacteria in the intestine of S. oramin facilitating the digestion of E. prolifera polysaccharides (EPP). Metagenomic sequencing analysis of the S. oramin intestinal microbiota revealed that E. prolifera diet increased the number of Firmicutes, replacing Proteobacteria to be the dominant bacteria. The proportion of Firmicutes increased from 38.8 to 58.6%, with Bacteroidetes increasing nearly fivefold from 5 to 23.7%. 16S rDNA high-throughput sequencing showed that EPP-induced Bacteroidetes increased significantly in the intestinal flora of S. oramin cultivated in vitro. Metatranscriptome analysis showed that EPP induced more transferase, polysaccharide hydrolase, glycoside hydrolase, and esterases expressed in vitro, and most of them were taxonomically annotated to Bacteroidetes. Compared with the aggregation of GH family genes in metagenomic sequencing analysis in vivo, EPP induced more CBM32, GH2, GT2, GT30, and GH30 families gene expression in vitro. In general, We found that the bacteria in intestinal tract of S. oramin responsible for digestion of E. prolifera were Firmicutes and Bacteroidetes, while Bacteroidetes was the dominant bacteria involved in EPP degradation in vitro cultures. Compared with in vivo experiments, only GH family genes were mostly involved, we detected a more complete and complex EPP degradation pathway in vitro. The results may benefit the further study of biodegradation of E. prolifera and has potential implications for the utilization of E. prolifera for biotechnology.
