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: Secondhand smoke (SHS) exposure remains a major public health concern, particularly for children who are highly vulnerable to the harmful effects of tobacco smoke. Despite comprehensive smoke-free policies in Hungary, children may still be exposed to SHS in private environments such as homes and outdoor settings. This study aimed to examine the prevalence and determinants of children's exposure to SHS in Hungary. Methods: This cross-sectional study used nationally representative data from the European Health Interview Survey (EHIS) 2019 conducted in Hungary. Of 964 eligible parents living with at least one child aged 0-15 years, 191 with missing outcome or covariate data were excluded, yielding a final analytic sample of 773 parents. Children's exposure was assessed from parental reports of exposure to conventional cigarette smoke and/or e-cigarette aerosol during the previous week. Three outcome variables were analyzed: indoor exposure, outdoor exposure, and overall exposure. Associations between parental demographic, socioeconomic, health, and lifestyle factors and children's exposure were examined using Pearson's chi-square tests and weighted multivariable logistic regression models. Results: Among the respondents, 8.8% reported indoor SHS exposure and 17.1% reported outdoor exposure among children, while 21.5% reported overall SHS exposure. Children's exposure to SHS was significantly associated with several parental characteristics. Lower household income, non-registered marital status, poorer parental oral health, and active smoking were associated with higher odds of indoor SHS exposure. Outdoor exposure was associated with urbanization, poorer oral health, and parental smoking. Overall SHS exposure was higher among children of parents with lower income, non-registered marital status, poorer oral health, poorer mental health, and active smoking status. Conclusion: A considerable proportion of children in Hungary remain exposed to SHS. Socioeconomic disadvantage, parental smoking, and parental health status are important determinants of children's SHS exposure. Targeted public health interventions focusing on smoking cessation and promoting smoke-free home environments are essential to reduce children's exposure to SHS.
