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 analyzed 10-yrs trends in dietary vitamin D intake and its food sources among Koreans. SUBJECTS/
methodsThis study included 61,734 individuals (≥ 3 yrs) from the 2013-2022 Korea National Health and Nutrition Examination Surveys. Daily vitamin D intake was assessed based on 24-h recall data. 10-yrs trends in 1) vitamin D intake, 2) vitamin D intake relative to the adequate intake (AI) of 2020 Dietary Reference Intakes for Koreans, and 3) proportions of individuals whose vitamin D intake below and above AI were analyzed using a complex sampling general linear model. Changes in food sources of vitamin D was also determined.
resultsVitamin D intake significantly decreased over 10 yrs with 3.2 μg/d in 2013 and 2.9 μg/d in 2022 (
conclusionVitamin D intake among Koreans has declined significantly over the past decade. Developing effective dietary guidelines considering sex and age is essential to improve vitamin D intake in this population.
