Gut microbiome-derived propionate reprograms alveolar macrophages metabolically and regulates lung injury responses in mice.
Article in Gut microbes, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Responses to lung injury can vary between individuals with the diet and gut microbiome representing two underappreciated sources for this variability. The gut microbiome can influence lung injury outcomes through the gut‒lung axis, but exactly how diet and its effects on the microbiota are involved remains unclear. We hypothesized that dietary fiber interventions would favor the presence of short-chain fatty acid (SCFA)-producing fermentative bacteria presence in the gut microbiome, thereby influencing the resting lung immunometabolic tone as well as influencing downstream responses to lung injury and infection. To test this hypothesis, we fed mice fiber-rich (FR) and fiber-free (FF) diets, and observed changes in the steady-state transcriptional programming of alveolar macrophages (AM). Next, we examined the effects of the FR and FF diets on murine responses to sterile and infectious lung injury
