Longitudinal Outcomes of a Smartphone Application to Prevent Drug Use Among Hispanic Youth.
Article in Journal of studies on alcohol and drugs, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
objectiveThis trial tested the efficacy of a smartphone application (app) designed to prevent drug use among Hispanic youth.
methodParticipants were recruited through online advertising and youth service agencies. The baseline sample (
resultsAnalyzed within an Arm by Time interaction model, follow-up data showed that compared with control-arm youth, intervention-arm youth reported (a) less increase in alcohol use from baseline to 2-year follow-up; (b) less increase in marijuana use from baseline to 2- and 3-year follow-ups; and (c) less increase in polydrug use from baseline to 1-, 2-, and 3-year follow-ups. Compared with youth in the control arm, intervention-arm youth reported (a) less depressed mood and improved skills for refusing offers of alcohol and tobacco at posttest; (b) higher self-efficacy and social self-efficacy at 1-, 2-, and 3-year follow-ups; (c) improved skills for refusing offers of marijuana at 2- and 3-year follow-ups; (d) higher media literacy at 2- and 3-year follow-ups; and (e) better coping skills at 3-year follow-up.
conclusionsThese longitudinal findings suggest that Hispanic youth can profit from tailored, skills-based content delivered via a smartphone app to prevent drug use.
