1 · What the graph read from it

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.

2 · The registry

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

Atmospheric bacteria and fungi are key components of urban bioaerosols, and their community structures are closely related to urban air quality, bioaerosol concentration, and environmental driving factors. However, the temporal dynamics and environmental drivers of bacterial and fungal community structures remain poorly characterized in megacities such as Shanghai, China. From November 2024 to November 2025, we conducted a year-long, cross-seasonal bioaerosol sampling and high-throughput DNA sequencing campaign to investigate the seasonal and diel variations, environmental covariation, and meteorological responses of atmospheric bacteria and fungi in Shanghai. The results show that seasonal transitions cannot significantly alter the α-diversity of bacterial or fungal communities, but significantly shift their community compositions, exhibiting a stronger differentiation for fungi than bacteria (PERMANOVA
