Associations of oxidative balance score and cognition in US older adults: A cross-sectional study of National Health and Nutrition Examination Survey (NHANES) 2011 to 2014.

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
Background: Oxidative stress is linked to cognitive decline in the elderly. Diet, as a key energy source, affects brain function and serves as a modifiable risk factor for cognitive decline. Objective: This study investigates the relationship between the Oxidative Balance Score (OBS), which reflects diet and lifestyle impact on oxidative stress, and cognitive function in older adults. Methods: This study utilized data from the National Health and Nutrition Examination Survey (NHANES) from 2011-2014, including 2716 participants aged 60 and older. Cognitive outcomes measured were the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) Word Learning test, Animal Fluency test, and Digit Symbol Substitution test. Linear regression models were used to assess the relationship between the OBS and cognitive performance, with stratification and sensitivity analyses conducted to explore these associations further. Results: Among 2716 participants, higher dietary OBS scores were linked to better cognitive test performance after adjusting for confounders. For example, the highest OBS quartile had a 4.35-point increase in CERAD immediate recall compared to the lowest quartile (OR: 4.35, 95% CI: 2.14-8.84, p = 0.001). Subgroup analyses showed this positive association across age groups and genders, though it was stronger among non-Hispanic white participants compared to other racial groups. Conclusions: Our findings indicate a positive correlation between OBS and cognitive function in older adults, suggesting that an antioxidant-rich diet and lifestyle may help prevent cognitive decline in this population. However, since this study is cross-sectional, further prospective research is needed to confirm these results.
