Interaction Between Composite Dietary Antioxidant Index and Alcohol Consumption on Cardiovascular Diseases: NHANES 2005-2018.
Article in Clinical cardiology, 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
backgroundCardiovascular diseases (CVDs) are a group of heart and blood vessel disorders and the leading causes of death worldwide. Few studies have focused on whether there is an interaction between the Composite Dietary Antioxidant Index (CDAI) combined with alcohol consumption on CVDs. We aimed to explore the association between CDAI, alcohol consumption, and CVDs, and whether there was an interaction.
methodsA total of 29459 participants aged over 20 years from the National Health and Nutrition Examination Survey (NHANES) in 2005-2018 were involved in the study. Six dietary factors were selected to score the CDAI. The association between CDAI, alcohol consumption, and CVDs were analyzed using binary logistic regression. Subgroup analysis and interaction tests were used to investigate whether this association was stable across populations.
resultsThe interaction between CDAI and alcohol consumption in relation to CVDs was observed. There was a statistically significant increased prevalence of CVDs in the CDAI 2 combined never-drinking subgroups and in the CDAI 1 combined never-drinking subgroups compared with the CDAI 3 combined moderate drinking group. Low CDAI levels were significantly and positively linked to CVDs prevalence within the never-drinking subgroup.
conclusionThe interaction between CDAI and alcohol consumption was found in our study. High levels of CDAI combined with moderate alcohol consumption may reduce the odds of CVDs.
