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
Background: Mental health conditions and substance use disorders commonly co-occur and adolescence is a period of increased risk for both. Adolescents with mental health conditions often begin using substances earlier than those without. Early initiation increases the risk of later substance use disorder. We propose to measure the impact of a peer-developed, primary care-based intervention to prevent substance use initiation among adolescents with mental health diagnoses and to evaluate responses to the intervention. Methods: This is a single-arm 12-month longitudinal unblinded pilot observational study. Adolescents aged 11-14 receiving pediatric primary care for diagnoses of depression, anxiety, or ADHD who have not yet initiated substance use will be eligible. The intervention involves quarterly assessments of substance use in the primary care office followed by viewing one of four 90-s videos targeting prevention topics like peer pressure for those who remain substance-free. The primary outcome is time to substance initiation, measured using the validated CRAFFT 2.1+N screener. Secondary outcomes include participant acceptance of the intervention, assessed by surveys, and tertiary outcomes will describe characteristics of participants who initiate substance use during the study. Analysis: We will use Kaplan-Meier survival estimates and descriptive statistics. Subgroup analyses will include age, sex, and diagnosis. Discussion: This trial targets a vulnerable population with increased risk for future substance use disorder. The intervention seeks to harness the protective effects of positive peer influence within the context of ongoing patient-provider relationships to promote delayed onset of substance use and inform feasibility and design of a future multi-site trial.
