Secondhand smoke and breast health awareness among Vietnamese American families in California: A mixed-methods study.
Article in Tobacco prevention & cessation, 2026. 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
Introduction: Tobacco exposure is a preventable breast cancer risk factor. High smoking rates among Vietnamese American (VA) men place VA women at elevated secondhand smoke exposure (SHSe) risk; yet research on the extent to which VA women are aware of SHSe and breast cancer risk is limited. Methods: This community-partnered, mixed-methods, cross-sectional study examined SHSe prevalences, knowledge, attitudes, and beliefs about SHSe as a breast cancer risk factor among VA women (aged 18-65 years) and explored multilevel factors contributing to SHSe within VA families in Southern California, December 2024 - January 2026. We recruited self-identifying VA women (n=179) via a community-based, snowball strategy for a 30 min survey, and then conducted 60 min one-on-one interviews with 22 VA individuals (11 family dyads). Results: Current SHSe prevalence was 43% (vs 25.2% nationally); 52.0% reported indoor SHSe during childhood. Only 63.7% had explicit home smoking rules, despite 99.4% believing SHSe affects children's health and 85.2% linking SHSe to increased breast cancer risk. A Rapid Group Analysis Process of the interview data revealed 3 themes, corroborating survey findings: 1) Religious/spiritual influences led participants to attribute health outcomes to fate or divine will, undermining preventive behaviors and beliefs, 2) A lack of available health information contributed to uncertain/diverging views on breast cancer causes; and 3) Non-smoker women expressing challenges navigating familial smoking-related tension while maintaining relational harmony. Conclusions: Our findings highlight the importance of family-centered communication while accounting for gender-related tension and family roles to promote cessation, breast cancer prevention and smoke-free spaces.
