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
Substance use during adolescence and young adulthood is a persistent public health problem. Social connectedness is associated with health, but research is needed to clarify the potential protective role of different aspects of social connectedness in primary prevention of substance use behaviors. This study explores associations between perceived social connectedness to two developmentally important social groups (friends and family) and various substances (alcohol, e-cigarettes, cigarettes, cannabis, and prescription medication) among adolescents and young adults. In addition, it examines how descriptive and injunctive norms within social groups affect associations between perceived social connectedness and substance use behaviors among adolescents and young adults. A statewide survey was conducted among 15,000 adolescents and young adults (12-25 years old, 52.6% female, 69.6% White) in North Carolina. Perceived social connectedness and substance use were assessed cross-sectionally, along with potential moderators (perceived friend and parent substance use and disapproval). Logistic regression was used to model associations with substance use. Moderation was examined with a regions-of-significance approach. Overall, perceived social connectedness was associated with lower odds of using most substances among adolescents and young adults. However, associations were moderated by perceptions of parental and friend substance disapproval and to a lesser extent by perceptions of parental and friend substance use behaviors. Findings suggest perceived connectedness to friends could potentially protect against substance use in the context of high perceived friend disapproval, whereas perceived connectedness to family is complex and may protect against substance use in the context of moderate/lower perceived parental disapproval of substance use. Longitudinal research is needed to understand the direction of associations with additional measures of social connectedness to help elucidate which aspects are protective and which are risky for adolescent and young adult substance use.
