Flavonoid intake, inflammation, and atherosclerotic cardiovascular disease risk in U.S. adults: a cross-sectional study.
Article in Nutrition & metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundThis study aimed to investigate the relationship between the dietary intake of total flavonoids and their six subclasses and the risk of atherosclerotic cardiovascular disease (ASCVD) in adults, and to evaluate the potential mediating effect of inflammation in this association.
methodsCross-sectional data from 3841 individuals participating in the National Health and Nutrition Examination Survey 2017-2018 were included in the analysis. Flavonoid intake was assessed using a 2-day dietary recall method, and ASCVD status was determined by extracting relevant information from the medical condition questionnaire. To determine the relationship between flavonoid intake and ASCVD risk, we employed logistic regression, subgroup, mediation, and restricted cubic spline analyses.
resultsIntake of flavan-3-ols, flavones, flavonols, and total flavonoids was negatively correlated with ASCVD risk. Subgroup analysis revealed that the association between flavonoid intake and ASCVD risk exhibits sex-specific differences, with the relationship being more pronounced among women. The significant associations between increased flavonoid intake and reduced ASCVD risk were observed in smokers, non-alcohol consumers, physically inactive individuals, those with hypertension. A nonlinear relationship was observed between the intake of total flavonoids, flavan-3-ols and flavonols and ASCVD risk. Additionally, high-sensitivity C-reactive protein (hs-CRP) and the neutrophil-to-lymphocyte ratio (NLR), inflammatory markers relevant to ASCVD, were found to mediate the association between flavonoid intake and ASCVD risk. Flavonoids demonstrated a dose‒response relationship with reductions in the levels of hs-CRP and the NLR.
conclusionsThis study indicates the inverse association between flavonoid intake, particularly flavan-3-ols, flavones, and flavonols, and the risk of ASCVD. It highlights the mediating role of CRP and NLR in this relationship. Furthermore, the study emphasizes the importance of considering lifestyle factors and sex when evaluating the cardiovascular benefits of flavonoids.
