B. adolescentis alleviates inflammation and suppresses PGE2 through remodling gut microbiota to attenuate pulmonary fibrosis in aging mice.
Article in NPJ science of food, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
The global burden of pulmonary fibrosis is increasing. Recent studies have shown that some pulmonary fibrotic lesions caused by COVID-19 infection may persist for a long time. Emerging evidence suggested a critical association between gut microbiota and pulmonary fibrosis. In this study, the clinical follow-up data from post-COVID-19 patients indicated that those with higher CT image scores were older, had a significantly lower Blautia and Bifidobacterium to Streptococcus ratio (B/S index). We examined whether Bifidobacterium adolescentis could attenuate bleomycin-induced pulmonary fibrosis in mice, with particular attention in the aging mice. Aging mice exhibited more severe pulmonary fibrosis after BLM induction, while the intervention of B. adolescentis attenuated the degree of pulmonary fibrosis in aging mice to a state similar to that of young mice. B. adolescentis alleviated inflammatory responses by enhancing the gut barrier, and reduced fibrotic marker expression (TGF-β, IL-17, α-SMA, Collagen I/III) by modulating PPAR and Th17 signaling pathways. Furthermore, B. adolescentis stabilized gut microbiota and increased the abundance of Bifidobacterium, Turicibacter, and norank_f_Desulfovibrionaceae, thereby suppressed the prostaglandin E2 (PGE2) and affected collagen deposition. B. adolescentis alleviates pulmonary fibrosis through the gut-lung axis by regulating PGE2/PPAR/Th17 signaling, providing a promising therapeutic approach for pulmonary fibrosis management.
