Effect of local youth-access regulations on progression to established smoking among youths in Massachusetts.
Article in Tobacco control, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
objectiveTo test whether community-level restrictions on youth access to tobacco (including both ordinances and enforcement) are associated with less smoking initiation or less progression to established smoking among adolescents.
designProspective cohort study of a random sample of adolescents in Massachusetts whose smoking status was assessed by telephone interviews at baseline and 2-year follow-up, and linked to a state-wide database of town-level youth-access ordinances and enforcement practices.
participantsA random sample of 2623 adolescents aged 12-17 years who lived in 295 towns in Massachusetts in 2001-2 and were followed in 2003-4.
main outcome measuresThe relationship between the strength of local youth access restrictions (including both ordinances and level of enforcement) and (1) never-smokers' smoking initiation rates and (2) experimenters' rate of progression to established smoking was tested in a multilevel analysis that accounted for town-level clustering and adjusted for potential individual, household and town-level confounders.
resultsOver 2 years, 21% of 1986 never-smokers initiated smoking and 25% of 518 experimenters became established smokers. The adjusted odds ratio (OR) for smoking initiation was 0.89 (95% CI 0.61 to 1.31) for strong versus weak youth-access policies and 0.93 (95% CI 0.67 to 1.29) for medium versus weak policies. The adjusted OR for progression to established smoking among adolescents who had experimented with smoking was 0.79 (95% CI 0.45 to 1.39) for strong versus weak local smoking restrictions and 0.85 (95% CI 0.50 to 1.45) for medium versus weak restrictions.
conclusionsThis prospective cohort study found no association between community-level youth-access restrictions and adolescents' rate of smoking initiation or progression to established smoking over 2 years.
