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
The extracellular space in plants, termed the apoplast, has a pH and sugar content that enables bacterial growth and represents a possible niche for the establishment of endophytic bacteria. Previous studies have investigated the effects of diazotrophic bacteria inoculation in sugarcane varieties, but it has not yet been analyzed how the microbial community of apoplast fluid of sugarcane is affected. High-throughput next generation sequencing of the 16S rRNA gene was used throughout this study to determine the effect of inoculation with a diazotrophic bacteria consortium, previously isolated from sugarcane, on the native bacterial population of sugarcane variety RB867515 grown in the field. The analyses were carried out 450 days after inoculation. The results revealed the presence of 22 phyla, with predominance of Proteobacteria phylum. It was observed that the inoculated consortium changed the indigenous bacterial community structure of sugarcane apoplast fluid by decreasing diversity and evenness, interfering in the composition of rare species. Microbial community composition analysis revealed differences between treatments. The differential abundance test showed there were 43 amplicon sequence variants (ASVs) which were relatively more abundant in the inoculated treatment, with predominance of the Sphingomonas genus. The predicted functions of the most abundant ASVs revealed the presence of genera related to plant growth promotion and protection against phytopathogens. Analysis to evaluate the occurrence of inoculated strains in the recovered data was not conclusive since the ASVs taxonomically close to the inoculated bacteria were observed in low abundance. The present study is the first report to elucidate the bacterial community in sugarcane apoplast fluid using a culture-independent approach. It demonstrated that the diazotrophic bacterial consortium interferes in the natural bacterial community in sugarcane variety RB867515.
