Six-month and one-year effects of project EX-4: a classroom-based smoking prevention and cessation intervention program.
Trial report in Addictive behaviors, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 15 papers, 3 of them syntheses that pooled 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.
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
objectiveThis study evaluated the efficacy of a version of Project EX that was adapted for implementation in the classroom context (Project EX-4). This paper reports the program outcomes based on pretest, six-month, and one-year follow-up surveys.
methodsAn 8 session classroom-based curriculum was tested with a clustered randomized controlled trial that involved a total of 1097 students in 6 program and 6 control alternative high schools. Weekly and monthly smoking was assessed at the three time points. Outcome effects were analyzed with multi-level random coefficients models.
resultsStudents in the program condition experienced a greater reduction in weekly smoking and monthly smoking, at 6-and-12-month follow-ups. The net change varied between -5.1% and -7.6%, comparing the program condition to the control condition.
conclusionsThe implementation of Project EX in a classroom setting produced decreases in smoking among students in the program, relative to those in the standard care control condition. It is likely that a classroom-based smoking prevention/cessation program can lead to lower overall smoking prevalence than a cessation program that is implemented in a school-based smoking cessation clinic format.
