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
introductionAdolescent suicidality poses a serious barrier to healthy growth and development. This study examines the association between secondhand smoke (SHS) exposure and suicidality among adolescents from multicultural families in South Korea, using a secondary analysis of the Korea Youth Risk Behavior Webbased Survey (KYRBS).
methodsThis cross-sectional study used pooled secondary data from the 2021 and 2024 waves of the KYRBS, a nationally representative survey of adolescents in South Korea, collected through self-administered questionnaires. This is a secondary dataset analysis of the KYRBS using logit regression models to assess the associations between the duration and setting-specific frequency of SHS exposure and suicidality among adolescents. The mediating role of perceived stress was examined using the Karlson-Holm-Breen (KHB) method.
resultsSHS exposure is significantly associated with increased suicidality likelihood among adolescents, with particularly strong associations observed in those from multicultural families. Among multicultural adolescents, each additional total day of SHS exposure is significantly associated with the likelihood of suicidal ideation (AOR=1.117; 95% CI: 1.084-1.151), suicide planning (AOR=1.095; 95% CI: 1.052-1.139), and suicide attempts (AOR=1.117; 95% CI: 1.069-1.168). SHS exposure showed a stronger association with suicidality in multicultural families versus non-multicultural families. A higher frequency of SHS exposure across multiple settings is significantly associated with elevated odds of suicidal ideation (AOR=1.422; 95% CI: 1.247-1.621), suicide planning (AOR=1.395; 95% CI: 1.153-1.689), and suicide attempts (AOR=1.524; 95% CI: 1.222-1.902). Further analysis reveals that perceived stress partially mediates the association between SHS exposure and suicidality among multicultural adolescents. Perceived stress indirectly mediated 23.19% of the effect of SHS exposure on suicide attempts. It also mediated 30.67% and 34.18% of the effects on suicidal ideation and planning, respectively.
conclusionsSHS exposure was associated with a higher likelihood of suicidality among adolescents, with this association observed in greater magnitude in adolescents from multicultural families. Moreover, perceived stress partially mediates the association between SHS exposure and suicide attempts among multicultural adolescents.
