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
Plant-microbe interactions play a critical role in maintaining plant health, enhancing soil fertility, and sustaining ecosystem functionality. Agave americana (Asparagales, Asparagaceae, L.), a crassulacean acid metabolism (CAM) species known for its remarkable drought tolerance and diverse industrial uses, represents a valuable model for exploring the ecological and functional dynamics of these associations. This study explores the diversity and functional potential of bacterial communities associated with A. americana and their role in promoting plant growth. A combination of culture-dependent techniques and metagenomic sequencing was employed to isolate and characterize rhizospheric and endophytic bacteria. Prominent bacterial genera identified included Acinetobacter, Bacillus, Rhizobium/Mesorhizobium, and Microbacterium. Metagenomic analyses revealed a high abundance of Actinobacteria, Proteobacteria, and Chloroflexi, highlighting their roles in nutrient cycling and organic matter decomposition. Plant growth-promoting assays demonstrated that Rhizobium sp. 34 A produced significant levels of indole-3-acetic acid (IAA), enhancing nutrient availability and plant growth. Mesorhizobium sp. 28 A had the greatest overall impact, significantly increasing total fresh weight, chlorophyll content, and sugar profiles, surpassing the effects of chemical fertilizers. Furthermore, Bacillus sp. T12C12, in combination with other plant growth-promoting bacteria (PGPB), exhibited the highest nitrogenase activity, as measured through acetylene reduction assays (ARA). These findings suggest that bacterial inoculants can enhance the nutritional and agronomic value of Agave species, which are of significant agro-industrial and food importance, providing a sustainable alternative to chemical fertilizers. This study offers valuable insights into sustainable agricultural practices by leveraging microbial communities to enhance crop productivity and resilience.
