Association between the oxidative balance score and preserved ratio impaired spirometry in US adults: NHANES 2007-2012.
Article in Frontiers in nutrition, 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
Background and aims: The relationship between oxidative stress (OS) and preserved ratio impaired spirometry (PRISm) remains unclear. We aimed to utilize the oxidation balance score (OBS), a validated instrument for assessing the overall OS status, to investigate the association between OBS and PRISm. Methods: We included data from 7,180 participants in the National Health and Nutrition Examination Survey (NHANES). The OBS was calculated using 20 components of diet and lifestyle. Binary logistic regression analyses were conducted to investigate the association between OBS and PRISm. Subsequent analyses were performed for non-smokers and smokers across different OBS levels. Results: OBS was inversely associated with PRISm in all models (all Conclusion: A lower OBS was associated with an increased incidence of PRISm, particularly among smokers, suggesting that OS may play a pivotal role in this relationship.
