Chemosynthetic ectosymbionts associated with a shallow-water marine nematode.
Article in Scientific reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 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
Prokaryotes and free-living nematodes are both very abundant and co-occur in marine environments, but little is known about their possible association. Our objective was to characterize the microbiome of a neglected but ecologically important group of free-living benthic nematodes of the Oncholaimidae family. We used a multi-approach study based on microscopic observations (Scanning Electron Microscopy and Fluorescence In Situ Hybridization) coupled with an assessment of molecular diversity using metabarcoding based on the 16S rRNA gene. All investigated free-living marine nematode specimens harboured distinct microbial communities (from the surrounding water and sediment and through the seasons) with ectosymbiosis seemed more abundant during summer. Microscopic observations distinguished two main morphotypes of bacteria (rod-shaped and filamentous) on the cuticle of these nematodes, which seemed to be affiliated to Campylobacterota and Gammaproteobacteria, respectively. Both ectosymbionts belonged to clades of bacteria usually associated with invertebrates from deep-sea hydrothermal vents. The presence of the AprA gene involved in sulfur metabolism suggested a potential for chemosynthesis in the nematode microbial community. The discovery of potential symbiotic associations of a shallow-water organism with taxa usually associated with deep-sea hydrothermal vents, is new for Nematoda, opening new avenues for the study of ecology and bacterial relationships with meiofauna.
