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
backgroundThe Arabian Sea is ecologically and environmentally significant due to its high biotic diversity and its potential role as a reservoir of emerging resistance determinants. However, molecular-level insights into the taxonomic composition, functional potential, and resistome of sediment associated communities from deep-sea seamount sediments remain limited. METHODS AND
resultsA metagenomic approach was employed to investigate the biotic composition, metabolic potential, resistome profiles, and physicochemical characteristics of two seamount sediment samples (SM1 and SM7) collected from the Arabian Sea. Distinct environmental conditions were observed, with SM1 enriched in inorganic nitrogen, whereas SM7 exhibited higher organic carbon content and pigment concentrations, indicating differences in substrate availability. These variations were consistent with differences in the community structure, with SM1 harbouring a less diverse assemblage dominated by Actinomycetota and fungi, while SM7 supported a broader community comprising Actinomycetota, diverse fungi, protists, metazoans, and a richer viral component. Functional annotation revealed enrichment of nitrogen metabolism pathways in SM1, whereas SM7 showed increased representation of carbohydrate metabolism and a higher proportion of novel gene content. Both sediment samples encoded antibiotic and heavy metal resistance genes; however, SM7 exhibited greater abundance and diversity of putative resistance-associated genes, including resistance to mupirocin, triclosan, and sulfonamides, along with broader metal resistance and stress response genes.
conclusionsThe results based on two samples demonstrate pronounced sample specific variation in community structure, metabolic potential, and resistome profiles across Arabian Sea seamount sediments. These findings highlight Arabian Sea deep-sea sediments as important molecular reservoirs of microbial diversity and adaptive potential shaped by local environmental conditions.
