A pilot proof-of-concept study of microbial and botanical diversity in honey samples from Necochea, Argentina.

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
Introduction: Honey is a complex biological matrix containing plant-derived, microbial, and viral components that reflect both environmental and hive-associated processes. Traditional methods for determining botanical origin, such as melissopalynology, have limitations in resolution and scope. In this context, untargeted shotgun metagenomics emerges as a promising integrative approach for comprehensive honey characterization. Methods: This pilot study explored the feasibility of applying an untargeted shotgun metagenomic approach to honey samples from Necochea, Buenos Aires province, Argentina. Two honey samples and a pollen control sample from Rosa chinensis were subjected to DNA extraction, shotgun library preparation, and sequencing on an Illumina NextSeq 500 platform. Results: The control sample showed exclusive assignment to Discussion: Given the limited sample size, these findings should be interpreted as exploratory and hypothesis-generating. Nevertheless, this proof-of-concept supports the potential of untargeted metagenomics as an integrated tool for the simultaneous characterization of botanical origin, microbial communities, and viral content in honey, offering advantages over targeted amplicon-based approaches. Future studies with larger and systematically designed cohorts will be necessary to validate and extend these observations.
