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
To examine the influence of diet on fish gut microbiota in channelized rivers, we characterized the gut microbial communities of fish with different feeding habits in the midstream of the Jialing River. The main findings are as follows: (1) 16S rRNA gene amplicon sequencing identified Firmicutes and Proteobacteria as the dominant phyla, with their relative abundances differing significantly among fish of distinct feeding habits. Firmicutes exhibited the highest relative abundance in carnivorous fish (93.41%), followed by omnivorous (53.39%) and herbivorous fish (29.3%). In contrast, Proteobacteria was most abundant in herbivorous fish (32.72%), with lower levels in omnivorous (22.43%) and carnivorous fish (4.81%). (2) The Kruskal-Wallis test indicated significant differences in the α-diversity of gut microbial communities among fish with distinct feeding habits (
