Adherence to the Dietary Index for Gut Microbiota and reduced risk of nephrolithiasis: a case-control study of Chinese adults.
Article in Frontiers in nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: Nephrolithiasis represents a substantial clinical burden worldwide. The Dietary Index for Gut Microbiota (DI-GM) assesses dietary impacts on gut microbiota. However, its association with the risk of nephrolithiasis remains unclear in Chinese adults. Methods: We conducted a case-control study using the Shenyang sub-cohort of the Tianjin Chronic Low-Grade Systemic Inflammation and Health (TCLSIH) cohort. Cases were 278 patients with nephrolithiasis. Controls were 556 healthy individuals, matched 1:2 by age and sex. Dietary intake was assessed using a validated food frequency questionnaire (FFQ) to calculate DI-GM scores. Multivariable conditional logistic regression evaluated the association. Restricted cubic spline (RCS) explored non-linear associations, and subgroup analyses were stratified by age and sex. Results: Higher DI-GM scores were significantly associated with lower risk of nephrolithiasis. After adjustment, the risk decreased progressively with increasing DI-GM scores (P for trend < 0.05). Individuals with DI-GM ≥ 8 had 83% lower risk than those scoring 0-5 (odds ratio [OR] = 0.17, 95% confidence interval [CI]: 0.08-0.36). The association was consistent across age and sex subgroups, with no non-linearity (P for non-linearity > 0.05). Conclusion: In Chinese adults, higher adherence to the DI-GM was associated with lower risk of nephrolithiasis. This finding suggests gut-friendly dietary patterns may be associated with a lower likelihood of nephrolithiasis. Future prospective studies are warranted to confirm this association.
