Associations between oxidative balance scores and heart failure among americans: NHANES (2007-2018).
Article in BMC cardiovascular disorders, 2025. 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
backgroundThe relationship between oxidative balance score (OBS) and heart failure (HF) is controversial. The OBS was used to assess systemic oxidative stress status, with higher OBS scores implying exposure to more antioxidants. This study aimed to explore whether OBS is associated with heart failure in US adults.
methodsA cross-sectional investigation was carried out using information from the National Health and Nutrition Examination Survey 2007-2018. The linear link between OBS and HF in adults aged ≥ 45 years was investigated using multivariate linear regression models. Interaction tests and subgroup analysis were also conducted.
resultsThe prevalence of HF was 3.84%. There was a significant negative relationship between OBS (OR: 0.96 ,95%CI: 0.95-0.98, P < 0.0001) and HF. In the fully adjusted model, compared to the lowest quartile of OBS, subjects in the highest quartile had a 45% lower likelihood of developing HF (OR: 0.55, 95% CI: 0.41-0.74, p < 0.0001). In stratified analysis, OBS and HF showed no obvious negative correlation.
conclusionOBS was strongly negatively associated with heart failure. The findings underline the significance of adhering to an antioxidant diet and lifestyle, which helps prevent heart failure.
