Associations Among Sleep Duration, Physical Activity, and Nutrient Intake in Korean Adults.
Article in Nutrients, 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/
objectivesThis study aims to investigate the relationship between sleep duration, physical activity, and nutritional intake of calories and vitamins to determine the interconnections among sleep, physical activity, and dietary habits.
methodsOverall, 5491 participants (male = 2347, female = 3144) aged ≥ 18 years were recruited from the first survey of the 2023 9th Korea National Health and Nutrition Examination Survey (KNHANES). All participants were assessed for sleep duration, physical activity levels, and intake of vitamin D, carbohydrates, protein, and fat.
resultsIn both sexes, participants with ≥8 h of sleep per day had significantly higher levels of moderate-intensity physical activity (male:
conclusionsSleep duration, physical activity, and nutrient intake (particularly vitamin D and protein) appear to be interrelated. Therefore, increasing daily physical activity and ensuring adequate intake of protein and vitamin D is recommended to maintain healthy sleep duration.
