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
introductionSecondhand smoke (SHS) and aerosol (SHA) exposures continue to be at unacceptably high levels in California, including among Latino communities, increasing the risk for chronic disease. California enacted legislation to reduce tobacco use and initiation, particularly among adolescents, through Senate Bill (SB) 793 which forbids the sale of flavored tobacco products in California. Our study evaluated exposures to smoking, including e-cigarette use and combustible smoking, and SHS and SHA among primarily foreign-born, Spanish-speaking Latina mothers and US-born middle and high school children via a survey in the greater San Francisco Bay Area in 2023-2024.
methodsUsing a longitudinal cohort of Latina mothers and their middle and high school children, surveys were used to assess attitudes towards SHS and SHA exposures and SB 793 including the ability to purchase flavored tobacco products. Means and standard deviations were used to characterize continuous predictors and outcomes and percentages for categorical ones. T-tests, Fisher's exact and chi-squared tests were use to assess possible associations between demographics and outcomes. All data was analyzed cross-sectionally.
resultsIn a sample of 115 predominantly Spanish-speaking mothers and US-born high school (n=50) and middle school (n=30) students in the greater San Francisco Bay Area, we found that >50% of high school students reported SHS and/or SHA exposures in the last 7 days. Unlike their mothers and middle school students, high school students often had exposures at school (in bathrooms, walkways and outdoors). High school students avoided SHS and SHA less than their mothers (34% vs 12%; p<0.01). High school students were more skeptical that SB 793 had changed the ability to source flavored tobacco products than their mothers or middle school students who believed in the efficacy of the law.
conclusionsFuture interventions should target students prior to high school as there were significant differences in attitudes based on age group. High schools have an unacceptably high amount of SHS and SHA exposure, and future interventions need to be high school-based.
