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 extensive utilization of antibiotics in both healthcare and agricultural sectors has precipitated an exponential surge in antibiotic resistance genes (ARGs) and antibiotic-resistant bacteria (ARBs) within environmental matrices, thereby posing formidable threats to ecosystem stability and human health. Given soil's pivotal role as a primary reservoir for ARGs and the inherent potential for these genes to translocate into agricultural produce, this study endeavors to evaluate the distribution patterns of ARGs and virulence factors (VFs) in soils designated for rice seedling cultivation. This study employed metagenomic sequencing to analyze antibiotic resistance genes (ARGs), virulence factors (VFs), and microbial communities in four rice seedling cultivation soils. The results revealed significant variations in microbial alpha diversity, community structure, ARGs, and VFs across soils, with multidrug resistance, glycopeptide resistance, and tetracycline resistance genes predominating. The inclusion of organic matter increased the complexity of the microbial network by increasing the levels of ARGs and VFs. Neutral community model analysis revealed that stochastic processes predominantly governed the assembly of microbial taxa, ARGs, and VFs, though ARGs were subject to stronger deterministic pressures. These communities were shaped by the pH, nitrogen, organic carbon content, electrical conductivity, and salinity of the soil. The core Actinobacteria genera acted as key vectors for ARGs and VFs dissemination. Our findings elucidate the complex interactions between microbes, ARGs, and VFs in cultivation soils and highlight that organic matter amendment, while enhancing fertility, can also increase the potential spread of microbial risk genes, underscoring the need for monitoring and managing ARGs and VFs in agricultural soils to mitigate public health risks.
