The lung microbiome in patients with HIV complicated with community-acquired pneumonia: a cross-sectional pilot study.
Article in Current research in microbial sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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: The composition of lung flora in HIV-combined community-acquired pneumonia (CAP) populations may be associated with the duration and severity of the disease. Additionally, a correlation may exist between lung flora balance and the body's autoimmune status. However, the number of studies in this area is limited. Therefore, we collected alveolar lavage fluid from 110 HIV-positive CAP patients at Beijing Ditan Hospital. We preliminarily explored the lung flora of this population using 16S amplicon analysis, and found some clues about the relationship between flora and immune status by comparing the flora of two groups of people with different immune status. Results: We found that the lung microbiome of HIV patients with CAP exhibited a "high-level aggregation-low-level dispersion" pattern across taxonomic hierarchies, this was characterised by dominant taxa at higher classification levels and dispersed, low-abundant taxa at lower levels. Microbial diversity in the AIDS group (CD4 Conclusions: Immune status profoundly influenced the composition and function of the pulmonary microbiome in HIV infection. AIDS patients exhibited pathogen-dominated, less stable microbial communities. These findings provided foundational insights into interactions among HIV, CAP, and the pulmonary microbiome, and informed the development of microbiome-targeted interventions.
