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

backgroundAdenoids play a pivotal role in immune system maturation during early childhood; however, pathological adenoid hypertrophy is associated with significant morbidity. Although infectious and immunological factors have been implicated, the role of the nasopharyngeal microbiome in adenoid hypertrophy remains incompletely understood.

methodsIn this cross-sectional study, the nasopharyngeal microbiome of 26 children diagnosed with symptomatic hypertrophic adenoids was compared with that of 30 age-matched healthy controls with non-hypertrophic adenoids. Microbial profiling was performed using 16S rRNA (ribosomal ribonucleic acid)gene sequencing. Alpha and beta diversity, core microbiome, network and differential abundance analyses were performed.

resultsAlpha diversity showed significant group differences (Fisher's alpha

conclusionsWhen compared with healthy controls, children with symptomatic hypertrophic adenoids exhibit a distinct nasopharyngeal microbiome characterized by altered microbial community structure and shifts in specific bacterial taxa. These findings support a potential role of the microbiome in the pathogenesis of adenoid hypertrophy.
