Interventions targeting adolescent substance use and misuse in South Asian Countries: A systematic review.
Synthesis in Drug and alcohol dependence, 2025. 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
backgroundThis systematic review synthesizes evidence from 10 intervention studies focused on substance use interventions for adolescents across eight South Asian countries.
methodsA literature search was conducted across MEDLINE (Ovid), Embase (Ovid), PsycINFO (EBSCO), Global Index Medicus, Web of Science (Clarivate), and Global Health (CAB Direct), covering studies from database October 1, 2016 to May 28, 2024. Only randomized control trials and quasi-experimental designs were included. The search strategy was pre-registered on the Open Science Framework.
resultsOut of 6356 studies identified, 4494 were screened, 193 were assessed for eligibility, and 10 studies were included in the review after consensus by two independent reviewers. Across these studies, which included 16,241 participants aged 9-18, seven were universal interventions, while three were targeted toward adolescents who were already using substances. Interventions primarily were conducted in school settings (n = 8) with a focus on tobacco, alcohol, inhalants, and supari use. Most studies demonstrated low selection and reporting bias, though performance and detection bias were unclear due to blinding limitations. Intervention duration ranged from 2 to 24 weeks and included between 2 and 119 sessions. Effectiveness was noted in four studies, three had mixed outcomes, two reported no significant effects, and one showed effects opposite of predicted outcomes.
conclusionThis review reveals varied intervention outcomes on adolescent substance use in South Asia, with positive effects in a subset of studies. These findings highlight the need for additional interventions with strong methodological rigor to reduce adolescent substance use and misuse in this region.
