Microbiome profiling reveals gut bacterial species associated with rapid lung function decline in people with HIV.
Article in Frontiers in immunology, 2025. 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
Background: People with HIV (PWH) have an increased risk of pulmonary comorbidities compared to people without HIV. The gut microbiome regulates host immunity and is altered in PWH. This study aims to determine potential associations between gut microbiome, lung function decline, and airflow limitation in PWH. Methods: PWH from the Copenhagen Comorbidity in HIV Infection (COCOMO) Study with available lung function testing and microbiome data were included (n=385). The gut microbiome was characterized using shotgun metagenomic sequencing. Associations between gut microbiome, rapid lung function decline, and airflow limitation were analysed in multivariable logistic regressions adjusted for traditional and HIV-associated risk factors for lung disease. Results: Several bacterial species were significantly enriched in PWH with rapid lung function decline, including opportunistic pathogenic bacterial species Conclusion: Associations between the gut dysbiosis index and rapid lung function decline and airflow limitation suggest a potential role of certain gut bacterial species in the pathogenesis of pulmonary comorbidities in PWH.
