Association between the dietary index of gut microbiota and abnormal bowel symptoms in U.S. adults: a cross-sectional study based on NHANES 2007-2010.
Article in BMC gastroenterology, 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
backgroundThe Dietary Index of Gut Microbiota (DI-GM) is a newly developed measure for assessing diet quality in relation to the diversity of the gut microbiome. However, whether it is associated with the risk of chronic constipation and chronic diarrhea remains unclear.
methodsWe analyzed data from 7,943 U.S. adults aged 20 years and older who participated in the 2007-2010 National Health and Nutrition Examination Survey (NHANES). Weighted logistic regression, subgroup analysis, and restricted cubic spline (RCS) models were used to assess the association between the DI-GM and abnormal bowel symptoms.
resultsA higher DI-GM score was significantly associated with a reduced risk of abnormal bowel symptoms. For each 1-point increase in the DI-GM, the risk of constipation decreased by 12.4% (OR = 0.876, 95% CI = 0.806-0.951, p = 0.002), and the risk of diarrhea decreased by 14.1% (OR = 0.859, 95% CI = 0.789-0.936, p < 0.001). Compared with the lowest DI-GM quartile, the highest quartile showed a markedly lower risk of both constipation (OR = 0.487, 95% CI = 0.340-0.696, p < 0.001) and diarrhea (OR = 0.480, 95% CI = 0.338-0.682, p < 0.001). RCS analysis indicated a significant linear association between the DI-GM and the risks of both constipation (nonlinear p = 0.686) and diarrhea (nonlinear p = 0.136).
conclusionsThe DI-GM was negatively associated with the prevalence of abnormal bowel symptoms. Further longitudinal studies are warranted to confirm these findings and to inform dietary strategies for gut health.
