Unraveling microbial life from a high-altitude hydrothermal system in the Andes plateau and their potential for nitrogen transformations.

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
Terrestrial hydrothermal systems provide a window for studying the biogeochemical interactions that occur in hot and gas-rich ecosystems resembling the conditions found in early life on Earth. The biogeochemical dynamics of the Andean hydrothermal systems in the Atacama Desert area are still understudied. Thus, we aimed to characterize the taxonomic composition and genomic potential of nitrogen transformations in a microbial community inhabiting a high-altitude hydrothermal system on the Altiplano Plateau of the Chilean Andes. Specifically, we sampled sediment and microbial mats in three ponds with water temperatures ranging from 42 to 64 °C. We found a high prevalence of photoheterotrophs, with differences in taxonomic composition and gene abundance between the microbial communities found in the sediment and microbial mats. Changes in physicochemical conditions, such as temperature and pH, and the concentrations of CO
