To quit or not to quit? estimating the causal effects of Türkiye's indoor smoking ban on the intentions to quit smoking.
Article in BMC public health, 2025. 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
backgroundSmoking bans aim to reduce tobacco use, but their long-term effectiveness remains uncertain. This study investigates short- and long-term causal effects of Türkiye's indoor smoking ban policy on the intentions to quit smoking among adults.
methodsUsing three waves of data (2008, 2012, and 2016) from the Global Adult Tobacco Survey (GATS), we analyse the changes in intentions to quit smoking before and after the implementation of indoor smoking ban policy in July 2009. The analysis includes data from 2008 as the pre-policy period, 2012 as the short post-policy period, and 2016 as a long post-policy period, to observe both initial and sustained effects.
resultsResults indicate a modest positive effect shortly after the ban's implementation, with a 2% increase in the log odds of intention to quit smoking in 2012 among the individuals exposed to the ban. However, by 2016, the effect appears to vanish, with a 11% decrease in the log odds of intention to quit smoking among those exposed to the ban over a prolonged period.
conclusionsOverall, the study suggests that while the smoking ban initially encouraged quitting intentions, its effect did not sustain over time, emphasizing the need for the controls of society compliance and of policy implementations.
