Association between Dietary Inflammatory Index and stroke prevalence among American adults: NHANES 2007 to 2016.
Article in Medicine, 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
Limited evidence links chronic inflammation to stroke prevalence, and the Dietary Inflammatory Index (DII) serves as a valid tool to quantify the inflammatory potential of diets. This cross-sectional study utilized data from the National Health and Nutrition Examination Survey 2007 to 2016, enrolling 27,250 adult participants. DII was calculated based on 24 dietary components and categorized into tertiles (Q1: anti-inflammatory diet, Q2: intermediate diet, Q3: pro-inflammatory diet). Stroke status was determined by participants' self-report of physician diagnosis, and covariates included demographic characteristics, socioeconomic status, lifestyle factors, and comorbidities. Weighted logistic regression models and restricted cubic spline analysis were employed to explore the association between DII and stroke. Among the participants, 981 (3.6%) had a history of stroke, with the mean DII significantly higher in stroke patients than in non-stroke patients (mean ± standard deviation: 1.65 ± 1.91 vs 0.96 ± 2.06, P < .001). In the minimally adjusted Model 2, as the DII grouping level increased, the odds of stroke prevalence also increased (odds ratio: 1.80, 95% confidence interval: 1.23, 1.91, P < .001). Restricted cubic spline analysis revealed a linear association between DII and stroke (nonlinear P = .5016), and subgroup analysis indicated significant interactions of this association with age and educational attainment (P < .05). In conclusion, a pro-inflammatory diet is positively associated with stroke prevalence in American adults, with a linear and stable relationship across different subgroups. Optimizing dietary inflammatory potential may be associated with lower stroke prevalence.
