Association between electronic screen time and childhood asthma: a cross-sectional study using NHANES 1999-2014 data.

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
backgroundChildhood asthma prevalence has risen globally, paralleling increased electronic screen exposure. This study investigated the association between electronic screen time (TV, computer, and total device use) and asthma risk in U.S. children.
methodsA cross-sectional analysis of 15,526 children (aged < 20 years) from NHANES (1999-2014) was conducted. Screen time (hours/day) was assessed via questionnaires. Asthma status was self-reported. Multivariable logistic regression, restricted cubic splines, and mediation analyses adjusted for demographics, obesity, income, and environmental factors.
resultsTotal screen time was positively associated with asthma risk (adjusted OR = 1.48 per hour increase, 95% CI:1.26-1.75, p < 0.001). Computer use ≥ 5 h/day conferred 30% higher asthma odds (OR = 1.30, 95% CI:1.06-1.60). Dose-response analysis showed elevated risk even at ≤ 2 h/day (OR = 1.18, 95% CI:1.04-1.34). Subgroup analyses (age, gender, body Mass Index) confirmed consistency (p < 0.05). No mediation by physical activity was observed.
conclusionsProlonged electronic screen time independently increased childhood asthma risk, emphasizing its role as a modifiable factor. Clinicians should integrate screen behavior assessments into asthma management. Future research should explore causal pathways, including circadian disruption and indoor pollutant interactions.
