High dietary inflammatory index is associated with an increased risk of overweight and obesity in adults: a meta-analysis of observational studies.

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 and objective: Unhealthy dietary patterns are recognized risk factors for obesity by promoting chronic low-grade inflammation. This meta-analysis aimed to examine whether higher DII scores are associated with overweight/obesity in adults. Methods: PubMed, Embase, ScienceDirect, Cochrane Library, and Web of Science databases were searched up to April 16, 2025. Standardized mean differences (SMDs) and 95% confidence intervals (CIs) were pooled for the highest versus lowest DII. Results: A total of 22 studies were included, comprising 19 cross-sectional studies and three prospective cohort studies. Meta-analysis of the cross-sectional studies indicated a small but significant positive association between DII and BMI (Cohen's d = 0.17; 95% CI: 0.09, 0.25), with significant heterogeneity (Q test, Conclusion: Higher DII is associated with overweight/obesity. Further studies are needed to clarify the temporal relationship and underlying biological mechanisms linking dietary inflammatory potential with overweight/obesity.
