A mechanistic test of nicotine replacement therapy sampling for smoking cessation induction.
Trial report in Psychology of addictive behaviors : journal of the Society of Psychologists in Addictive Behaviors, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 22 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
Studies that explore the mechanisms of treatment effect are needed in the area of smoking cessation induction, the primary goal of which is to promote the occurrence of a quit attempt among individuals who report little interest in smoking cessation. This study tested the mediational effect of 5 psychological variables (motivation to quit, abstinence self-efficacy, knowledge of nicotine replacement therapy (NRT), and both positive and negative attitudes toward NRT) on the relationship between NRT sampling and smoking outcomes. Adults who reported low levels of intention to quit in the next month (n = 593) were recruited for a nationwide randomized clinical trial of NRT sampling. Participants provided self-report data via telephone interview on multiple occasions, with the final follow-up at 6 months. Motivation to quit, and to a lesser degree, abstinence self-efficacy at the end of the 6-week intervention best accounted for the effect of NRT sampling as a promoter of quit attempts, smoking reduction, and 7-day point prevalence abstinence. Providing smokers with free NRT samples, in addition to encouraging them to engage in temporary abstinence, results in meaningful change in motivation and self-efficacy, which in turn influence smoking outcomes. Cessation induction interventions should aim to increase motivation to quit and abstinence self-efficacy, above and beyond any efforts to increase knowledge or prompt attitudinal shifts.
