Cocaine use is declining among emerging adults in the United States: Trends by college enrollment.
Article in Addictive behaviors, 2019. 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
backgroundThe difference in cocaine use between student and non-student emerging adults is not well understood, despite the longstanding assumption that college is protective against use.
objectiveTo describe trends in cocaine use among emerging adults by college enrollment.
methodsUsing cross-sectional, nationally-representative data from the National Survey on Drug Use and Health (2002-2016), we estimated the prevalence of four cocaine use indicators by year among emerging adults (ages 18-22) and stratified by college enrollment. We tested for linear and quadratic trends over time.
resultsFrom 2002 to 2016, 11.7% reported lifetime cocaine use, 5.8% reported past 12-month use, 1.7% reported past 30-day use, and 1% had a use disorder in the past 12-months. We observed significant linear decreases in all four use indicators over time (Lifetime: β = -0.20, Past 12-months: β = -0.17, Past 30-days: β = -0.22, Past 12-months disorder: β = -0.37). Students had lower rates of cocaine use than non-students, although prevalence estimates were more similar between groups for past 12-month (Students:5.3%, 95% CI:5.0-5.5; Non-students:6.3%, 95% CI:6.1-6.5) and past 30-day use (Students:1.6%, 95% CI:1.4-1.7; Non-students:1.8%, 95% CI:1.7-1.9) than for lifetime use (Students:9.4%, 95% CI:9.1-9.7; Non-students:13.8%, 95% CI:13.5-14.1).
conclusionsCocaine use has declined among emerging adults since the early 2000s. The college environment appears compensate for early life differences in cocaine use risk between students and non-students, closing the gap between groups for recent indicators of cocaine use. Given the severe health consequences associated with cocaine use, more public health attention to this issue is needed.
