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) exposure is a significant cause of illness. This study aimed to explore the awareness of SHS-attributed illnesses and the legal control of the Tobacco Product Control (TPC) Act 2017 among the local people living in Meung district, a municipality of Songkhla Province, Thailand.
methodsThis quantitative and qualitative study was conducted in 3 marketplaces and 6 public bus terminals in a southern province of Thailand between November 2021 and September 2022. A total of 330 volunteers were enrolled for the quantitative analysis. Meanwhile, 13 local government officers (LGOs), 2 market visitors, and 5 public vehicle passengers were interviewed for qualitative analysis to evaluate applicability of the law in this province. We collected the participants' general demographics, prevalence of secondhand smoke (SHS) exposure, knowledge about SHS-attributed diseases, and awareness of the law. Chi-squared test was used to assess the associations between demographics and knowledge of SHS-attributed diseases and awareness of the legal restrictions regarding SHS exposure (p<0.05). Thematic analysis for evaluating applicability of the law was conducted from the interviews.
resultsTobacco smell was experienced more frequently than witnessing smokers in marketplaces (49.8% vs 30.0%) and on public vehicles (45.5% vs 20.7%). The mean ± SD scores of knowledge regarding the law were low (marketplace, 4.09 ± 1.61; bus, 4.07 ± 1.69), while that of SHS-attributed health harms were moderate (marketplace, 6.31 ± 2.14; bus, 6.30 ± 1.64). Age, education level, and religion had significant associations with knowledge about SHS-attributed diseases (p=0.001, <0.001, <0.001, respectively), while age and education level were significantly associated with awareness of the law (p<0.001). We found weaknesses in the collaboration of LGOs. Inadequate resources and a high volume of routine workload were the attributed barriers.
conclusionsEnhancing knowledge about SHS-attributed illnesses, awareness of the SHS control law, and strengthening public engagement are crucial for SHS exposure control. The collaboration between the local people and LGOs for effective SHS control is advocated.
