Secondhand smoke exposure and sleep disturbances among Korean adolescents: A nationally representative cross-sectional study.
Article in Tobacco induced diseases, 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
introductionInadequate sleep duration among adolescents is increasingly recognized as a significant public health concern, with potential associations with various environmental exposures. This study investigates the association between secondhand smoke (SHS) exposure and sleep duration in Korean adolescents.
methodsThis study employed a pooled cross-sectional design using data from the nationally representative Korea Youth Risk Behavior Web-based Survey from 2021 to 2024 (n=195664). This study analyzed self-reported sleep duration (hours/minutes) from the Korea Youth Risk Behavior Web-based Survey (KYRBS). Ordinary least squares regression models were used to analyze the association between SHS exposure days and sleep duration, adjusting for individual, school, and family-level control variables. The moderating effect of tobacco use was examined through interaction terms.
resultsSHS exposure demonstrated a significant negative association with adolescent sleep duration. After full adjustment for control variables, each additional day of SHS exposure was associated with a reduction in weekly average sleep duration (β= -0.027; 95% CI: -0.029 - -0.024, p<0.01), weekday sleep duration (β= -0.030; 95% CI: -0.03 - -0.028, p<0.01), and weekend sleep duration (β= -0.018; 95% CI: -0.023 - -0.013, p<0.01). Tobacco use significantly moderated this relationship, with the interaction term showing positive coefficients across all sleep duration models.
conclusionsSHS exposure significantly associated with sleep deprivation among Korean adolescents, with this association being influenced by individual tobacco use habits.
