Association between a novel Dietary Index for Gut Microbiota and periodontitis: a cross-sectional study.

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 gut microbiota and periodontitis have attracted increasing research interest. The Dietary Index for Gut Microbiota (DI-GM), a novel metric for assessing gut microbiome diversity, has not yet been investigated in relation to periodontitis. Methods: This cross-sectional study analyzed data from the 2009-2014 National Health and Nutrition Examination Survey including 9,978 participants aged 30-80 years who had periodontal examination records. Participants were categorized into two groups: no periodontitis ( Results: A higher DI-GM score was inversely associated with periodontitis (odd ratio [OR] = 0.94, 95% confidence interval [CI]: 0.91-0.97). Similarly, a higher beneficial microbiota score was linked to a lower prevalence of periodontitis (OR = 0.90, 95% CI: 0.87-0.94). After adjustment, DI-GM remained inversely associated with moderate (OR = 0.94, 95% CI: 0.91-0.97) and severe periodontitis (OR = 0.89, 95% CI: 0.85-0.94; both Conclusion: The newly proposed DI-GM demonstrated an inverse association with the prevalence of periodontitis, with BMI acting as a significant mediator in this relationship.
