Microbial ecology of subsurface granitic bedrock: a humid-arid site comparison in Chile.
Article in ISME communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Subsurface microorganisms face extreme challenges such as anoxic, xeric, and oligotrophic conditions. In igneous systems, nutrient limitation is critical, as biomass input relies on surface-derived fluids via tectonic fractures. Despite growing interest in subsurface habitats, little is known about ecosystems beneath arid landscapes, where surface water input is limited by the low annual precipitation. This study compares granitic subsurface environments beneath arid and humid surface ecosystems, highlighting the link between surface climate and subsurface biodiversity. DNA was extracted from granitic subsurface rocks recovered from two endmember sites along a north-south climate gradient in Chile's Coastal Cordillera. Microbial communities inhabiting down to 55 m deep subsurface rocks were characterized using 16S rRNA amplicon and shotgun metagenomic sequencing. We identified an abundant and potentially active subsurface community below both climates dominated by heterotrophic bacteria, including
