Association Between the Dietary Index for Gut Microbiota and Frailty: Mediating Role of Body Mass Index.
Article in Food science & nutrition, 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
Dietary composition and quality have been linked to the onset of frailty. Although the recently developed Dietary Index for Gut Microbiota (DI-GM) offers a means to evaluate diet quality based on its impact on the gut microbiota, its relevance to frailty has yet to be determined. This cross-sectional study utilized data from the NHANES collected between 2007 and 2020. DI-GM scores were determined based on 14 dietary components, with higher scores indicating a diet more supportive of gut microbiota health. Frailty was evaluated using a validated 49-item frailty index, with frailty defined as a score of 0.21 or higher. Weighted logistic regression, restricted cubic spline models, and mediation analyses were employed to examine the relationship between DI-GM scores and frailty. A total of 27,026 eligible participants were included in the analysis. Higher DI-GM scores were significantly associated with a lower risk of frailty. After full adjustment (Model 3), each one-point increase in the DI-GM scores corresponded to a 4% reduction in the odds of frailty (OR: 0.96, 95% CI: 0.92-1.00). Compared to the lowest quartile (Q1), individuals in the highest quartile (Q4) demonstrated significantly lower odds of frailty (OR: 0.81, 95% CI: 0.67-0.99). A nonlinear relationship between DI-GM scores and frailty was identified (
