Association Between Ultra-Processed Food Consumption and Frailty in Korean Older Adults.
Article in Nutrients, 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
BACKGROUND/
objectivesPopulation aging is accelerating worldwide, and frailty has emerged as an important health concern among older adults. Although ultra-processed food (UPF) consumption has been associated with a range of adverse health outcomes, evidence on its relationship with frailty among Korean older adults remains limited. This study examined the cross-sectional association between the proportion of total energy intake derived from UPFs and frailty among Korean adults aged 65 years or older.
methodsWe analyzed data from 9861 adults aged ≥65 years who participated in the 2014-2019, 2022, and 2024 Korea National Health and Nutrition Examination Survey cycles, in which the variables required to assess frailty were available. Dietary intake was assessed using a 24-h dietary recall, and foods were classified according to the NOVA food classification system. Frailty was defined using a modified Fried frailty phenotype. Survey-weighted multivariable logistic regression models were used to examine associations between UPF energy contribution and frailty, and restricted cubic spline models were used to evaluate the dose-response relationship.
resultsIn the fully adjusted model, participants in the highest quartile of UPF energy contribution had 31% higher odds of frailty than those in the lowest quartile (odds ratio [OR] = 1.31, 95% confidence interval [CI]: 1.08-1.59;
conclusionsHigher UPF consumption was positively associated with frailty among Korean older adults, particularly with low physical activity. These findings highlight the relevance of UPF consumption to frailty in an older population with relatively low levels of UPF intake.
