A community intervention to reduce alcohol consumption and drunkenness among adolescents in Sweden: a quasi-experiment.
Trial report in BMC public health, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis 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
backgroundSeveral studies have examined the effect of community interventions on youth alcohol consumption, and the results have often been mixed. The aim of this study is to evaluate the effectiveness of a community intervention known as the Öckerö Method on adolescent alcohol consumption and perceived parental attitudes towards adolescent drinking.
methodThe study is based on a quasi-experimental design, using matched controls. Self-report studies were conducted among adolescents in grades 7-9 of compulsory education in four control and four intervention communities in the south of Sweden in 2016-2018. Baseline measures were collected in autumn 2016 before the intervention was implemented in the intervention communities. Outcomes were the adolescents' alcohol consumption, past-year drunkenness, past-month drunkenness and perceived parental attitudes towards alcohol.
resultsEstimating Difference-in-Difference models using Linear Probability Models, we found no empirical evidence that the intervention has any effect on adolescents' drinking habits, or on their perceptions of their parents' attitudes towards adolescent drinking.
conclusionThis is the first evaluation of this method, and we found no evidence that the intervention had any effect on the level of either young people's alcohol consumption or their past-year or past-month drunkenness, nor on their parents' perceived attitudes toward adolescent drinking. A further improvement would be to employ a follow-up period that is longer than the three-year period employed in this study.
