Australian Communities That Care (CTC) intervention: Benefit-cost analysis of a community-based youth alcohol prevention initiative.
Article in PloS one, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundInternationally, adolescent alcohol consumption has been a major community concern for decades. Globally, there is a growing array of interventions aimed at preventing youth alcohol-related problems. Notably, the Communities that Care (CTC) process in the USA has proven to be a cost-effective intervention, leading to a reduction in adolescent alcohol-related problems. In Australia, the CTC trial has shown positive outcomes such as reduced adolescent alcohol and drug use, antisocial behaviors, and the availability of alcohol in the community. To encourage wider adoption, it is essential to ascertain the cost-effectiveness of the Australian CTC trial and its potential impact on addressing youth alcohol problems.
methodWe conducted a limited societal perspective benefit-cost analysis focused on reducing adolescent (aged 10-14) alcohol use in the initial four CTC communities in Australia, spanning 2001 to 2015. To ensure accuracy, estimated benefits were adjusted for joint effects to prevent the double counting of the benefits over time.
resultsThe Australian CTC trial, as an adolescent alcohol prevention strategy, demonstrates robust economic credentials, delivering a return of AUD 2.6 for each dollar invested. The cost savings resulting from the reduction in alcohol consumption were estimated at AUD 123 per youth per 15 years and AUD 8 per person per year. The average cost of the CTC trial amounted to AUD 48 per youth over 15 years and AUD 3 per youth per year. The largest contribution to primary benefits were reductions in crime and violence with 93% of the total benefits.
conclusionsThis study makes a valuable contribution to the international economic evidence related to youth alcohol prevention initiatives. The results affirm the strong cost-effectiveness potential of the initial CTC trial implementation in Australia. Moreover, conducting further cost-benefit modelling for additional outcomes and beyond the intervention's timeframe is likely to enhance the economic viability of the CTC trial.
