Human Contact Frequency as a Dominant Ecological Driver of Fungal Community Assembly and Homogenization in Public Built Environments.
Article in Journal of microbiology and biotechnology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
As modern populations spend the majority of their time indoors, understanding indoor microbial ecology is crucial for public health. While research has addressed abiotic pollutants, the ecological dynamics of surface-associated mycobiomes remain insufficiently understood. This study assessed fungal communities across 25 types of public facilities in South Korea to evaluate the relative influence of environmental parameters and human-driven factors. A total of 327 surface samples from six surface types (handles, tables, chairs, walls, pillars, floors) were analyzed using internal transcribed spacer (ITS) sequencing, yielding 27 million reads and 31,721 amplicon sequence variants (ASVs). Although temperature and humidity significantly correlated with airborne fungal concentration, they exerted minimal influence on community diversity and structure. Instead, the intensity of human contact with indoor surfaces emerged as a primary driver of fungal community composition. We found that the relative abundance of the human-associated genus
