Association between composite dietary antioxidant index and the prevalence of periodontitis: results from NHANES 2009-2014.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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 antioxidant system of periodontal tissue is unbalanced in periodontitis, and appropriate supplementation of antioxidants can effectively prevent or alleviate periodontal tissue damage. However, a dearth of research exists on the association between dietary antioxidant intake and the prevalence of periodontitis.
methodsSix dietary antioxidants (vitamins A, C, and E, zinc, selenium, and carotenoids) were extracted from two 24-h recall interviews utilizing data from the National Health and Nutrition Examination Survey (NHANES) conducted between 2009 and 2014. The composite dietary antioxidant index (CDAI) made calculations using data on the intake of these six dietary antioxidants. Periodontitis severity was categorized into mild, moderate, and severe classifications based on established consensus criteria. Additionally, a restricted cubic spline (RCS) regression model was applied to evaluate the potential non-linear dose-response relationship between CDAI and periodontitis prevalence.
resultsA total of 9,378 adults were included in this analysis, of which 4,755 had periodontitis. Individuals within the highest CDAI quartile demonstrated a diminished prevalence of total periodontitis compared to those in the lowest quartile (OR = 0.70 [0.53-0.93], P
conclusionElevated dietary antioxidant intake is associated with a diminished prevalence of periodontitis. These findings underscore the potential role of antioxidants in periodontal health.
