1 · What the graph read from it

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.

2 · The registry

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/

objectivesThe rate of breakfast skipping among Korean young adults has increased rapidly, but its association with the dietary macronutrient composition remains unclear. Using diet-quality-based low-carbohydrate diet (LCD) and low-fat diet (LFD) scoring systems, this study primarily examined the association between breakfast skipping and 6 diet-quality scores. As a secondary analysis, this study assessed how these scores, and breakfast skipping itself, were related to metabolic syndrome and its components, to gauge the metabolic relevance of the scores. SUBJECTS/

methodsThis cross-sectional study analyzed 2,872 adults aged 19-39 yrs from the 2021-2023 Korea National Health and Nutrition Examination Survey, excluding those diagnosed or treated for chronic disease, implausible energy intake, or pregnancy/lactation. Breakfast skipping was defined as no intake reported as "breakfast" in the 24-h recall. The LCD and LFD scores were calculated using the method proposed by Shan

resultsAmong the participants, 52.2% (n = 1,500) skipped breakfast. After adjustment, the skippers had significantly higher unhealthy LCD scores (β = 1.19) and lower overall LFD (β = -0.67) and healthy LFD (β = -1.55) scores than those who did not skip breakfast. A comparison of the extreme quartiles showed that the overall LCD score was inversely associated with abdominal obesity (odds ratio [OR], 0.56) and elevated triglycerides (OR, 0.60), a healthy LCD score with elevated triglycerides (OR, 0.70), and an unhealthy LCD score with abdominal obesity (OR, 0.59) and elevated blood pressure (OR, 0.50).

conclusionBreakfast skipping was associated with a lower-quality composition of the same-day diet. Exploratory secondary analyses showed that most associations with metabolic syndrome components were not significant. Nevertheless, the findings should be interpreted with caution because this study was cross-sectional.
