1 · What the graph read from it

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.

2 · The registry

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

objectiveWe assessed changes in secondhand smoke (SHS) exposure in workplaces and public venues in Poland over a 9-year period following the adoption of a smoke-free policy in Poland in 2010.

designSix waves of cross-sectional surveys were carried out between 2009 and 2019.

participantsA nationally representative sample of adult Polish residents (age 15 years and older) was surveyed.Survey respondents self-reported SHS exposure in the workplace and 12 different public venues. Data were analysed separately for samples consisting of (1) all respondents and (2) non-smokers only.SHS exposure was defined based on self-report, which may invoke error such as demand bias or recall bias and study protocol do not include participation of paediatric populations that are key limitations of this study.

resultsWithin a year of adopting the smoke-free policy in 2010, the proportion of non-smokers exposed to SHS in Polish workplaces decreased by more than half (from 19.2% in 2009 to 9.5% in 2011). Over 10 years, a substantial reduction in SHS exposure was observed in all public venues. The highest decrease in SHS exposure was observed in transport services (decreased from 45.7% to 11.7% among all respondents and from 44.2% to 11.7% among non-smokers) and in bars/pubs (SHS exposure decreased from 45.0% to 7.0% among all respondents and from 39.4% to 7.0% among non-smokers).

conclusionsThis study demonstrates the substantial success of a national smoke-free law. Nevertheless, smoke-free laws must continue to be refined in terms of their legal boundaries as well as implementation strategies to eliminate disparities in SHS exposure in certain types of venues.
