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
Understanding microbial dispersion in the atmosphere is essential for studying microbial biogeography and ecosystem dynamics under global change. Airborne bacterial communities, shaped by exchanges between atmosphere and Earth's surface, can originate from diverse sources and vary with meteorological conditions and air mass trajectories. In this study, we assessed airborne microbial communities in Antarctica at regional and local scales. Air samples were collected during the austral summer at two Antarctic Specially Protected Areas (ASPAs): Byers Peninsula (Livingston Island, South Shetland Islands) and Avian Island (Marguerite Bay). Bacterial composition was analysed through 16S rRNA gene sequencing using amplicon sequence variants (ASVs). Additionally, back-trajectories of the sampled air parcels were simulated with HYSPLIT. A core community was identified in 80% of Byers Peninsula samples, representing 57.91% of total ASVs. Notably, 79.4% of ASVs matched soil bacteria from the same location, suggesting a strong influence of local sources. Communities from Byers Peninsula and Avian Island showed low overall similarity. However, one sample from Byers resembled the Avian sample, likely due to similar air mass back-trajectories. These findings suggest that airborne bacterial communities are shaped by both local ecosystems, and broader regional or continental processes, such as long-range trajectories carrying microorganisms from distant locations.
