Presence of Gastric Pepsinogen in the Trachea Is Associated with Altered Inflammation and Microbial Composition.
Article in Infection and immunity, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
Gastroesophageal reflux is a common gastrointestinal issue that can lead to aspiration and contribute to respiratory problems. Little is known about how reflux can alter the respiratory microenvironment. We aimed to determine if the presence of gastric pepsinogen in the trachea was associated with changes in the microbial and inflammatory microenvironment. A pediatric cohort at high risk of reflux aspiration was prospectively recruited, and the tracheal microenvironment was examined. Pepsinogen A3 (PGA3) and cytokines were measured. The microbiome (bacterial and fungal) was profiled using 16S rRNA and internal transcribed spacer 2 (ITS2) amplicon sequencing. Increased bacterial richness and an altered composition driven by an enrichment of
