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

backgroundGiven concerns that screen time may impact dietary habits, this study investigated the association between screen time and dietary intake among adolescents in the United States.

methodsWe analyzed a prospective cohort (N = 6485, 47.3% female, age: 12 ± 0.7 years) from the Adolescent Brain Cognitive Development (ABCD) Study, using data from Year 2 (2018-2020) and Year 3 (2019-2021). Multinomial logistic regression models estimated the associations between participant-reported screen time (watching television shows and videos, playing video games, socializing, browsing the internet, and total screen time (hours/day)) and parent/participant-reported intake of various food/nutrient categories 1 year later (Year 3). We adjusted for age, sex, race and ethnicity, household income, parent education, average daily kilocalorie intake, respective food or nutrient, and study site (Year 2).

resultsEach additional hour of most screen time modalities was prospectively associated with higher odds of consuming fewer fruits, vegetables, whole grains, legumes, fiber, and dairy, and higher glycemic index, and higher odds of consuming more added sugars and a higher polyunsaturated fats ratio 1 year later.

conclusionThese findings highlight the need for parental guidance and clinical interventions to support screen time habits and promote healthy dietary choices among adolescents. IMPACT: This study examines the association between contemporary screen time modalities and dietary intake 1 year later in a demographically diverse U.S. sample of early adolescents. Most screen time modalities, such as total screen time and watching television shows and videos, were prospectively associated with higher odds of consuming fewer fruits, vegetables, whole grains, legumes, and fiber 1 year later. Greater total screen time and time spent socializing were prospectively associated with higher odds of a higher polyunsaturated fats ratio 1 year later.
