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

objectiveTo explore between-country differences and within-country trends over time in smokers' reasons for thinking about quitting and the relationship between reasons and making a quit attempt.

methodsParticipants were nationally representative samples of adult smokers from the UK (N=4717), Canada (N=4884), the USA (N=6703) and Australia (N=4482), surveyed as part of the International Tobacco Control Four Country Survey between 2002 and 2015. Generalised estimating equations were used to evaluate differences among countries in smokers' reasons for thinking about quitting and their association with making a quit attempt at follow-up wave.

resultsSmokers' concern for personal health was consistently the most frequently endorsed reason for thinking about quitting in each country and across waves, and was most strongly associated with making a quit attempt. UK smokers were less likely than their counterparts to endorse health concerns, but were more likely to endorse medication and quitline availability reasons. Canadian smokers endorsed the most reasons, and smokers in the USA and Australia increased in number of reasons endorsed over the course of the study period. Endorsement of health warnings, and perhaps price, appears to peak in the year or so after the change is introduced, whereas other responses were not immediately linked to policy changes.

conclusionsDifferences in reasons for thinking about quitting exist among smokers in countries with different histories of tobacco control policies. Health concern is consistently the most common reason for quitting and the strongest predictor of future attempts.
