Robust, Open-Source and Automation-Friendly DNA Extraction Protocol for Hologenomic Research.
Article in Molecular ecology resources, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Global efforts to standardise methodologies benefit greatly from open-source procedures that enable the generation of comparable data. Here, we present a modular, high-throughput nucleic acid extraction protocol standardised within the Earth Hologenome Initiative to generate both genomic and microbial metagenomic data from faecal samples of vertebrates. The procedure enables the purification of either RNA and DNA in separate fractions (DREX1) or as total nucleic acids (DREX2). We demonstrate their effectiveness across faecal samples from amphibians, reptiles and mammals, with reduced performance observed on bird guano. Despite some variation in laboratory performance metrics, both DREX1 and DREX2 yielded highly similar microbial community profiles, as well as comparable depth and breadth of host genome coverages. Benchmarking against a commercial kit widely used in microbiome research showed comparable recovery of host genomic data and microbial community complexity. Our open-source method offers a robust, cost-effective, scalable and automation-friendly nucleic acid extraction procedure to generate high-quality hologenomic data across vertebrate taxa. The method enhances research comparability and reproducibility by providing standardised, high-throughput, open-access protocols with fully transparent reagents. It is designed to integrate automatised pipelines, and its modular structure also supports continuous development and improvement.
