Role of smoking intention in tobacco use reduction: A mediation analysis of an effective classroom-based prevention/cessation intervention for adolescents.
Article in Addictive behaviors, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
introductionAlthough some school-based tobacco cessation and prevention programs have been proven to be effective, there remains a lack of understanding of how these programs succeed.
methodsThis longitudinal study aimed to test smoking intention as a mediator of Project EX's intervention efficacy to reduce tobacco use. Using a computerized random number generator, six high schools located in the Mediterranean coast were randomly selected to participate in the program condition (Spanish version of Project EX) or the waiting-list control group with baseline, immediate-posttest, and 12-month follow-up assessments. At baseline, 685 adolescents aged 14-20 years (mean age: 14.87; SD = 0.92; 47.4% were females) were evaluated using self-administered tests of tobacco, and smoking intention. A biomarker of smoke inhalation, a measurement of exhaled carbon monoxide (ECM), was used. Mediation analyses were conducted using the PROCESS v2.12 macro for Windows.
resultsProject EX had a significant effect on smoking intention. Indirect effects indicated that Project EX reduced the ECM level, and number of cigarettes used.
conclusionsThis is the first Spanish study that explored intention as a mediator of the long-term efficacy of Project EX to reduce tobacco use in adolescents. Results suggested that interventions that reduce consumption intention at short-term are more likely to be successful in decreasing tobacco use in the long-term.
