Identification of distinct stimulant use trajectories and patterns of overdose.
Article in Addictive behaviors reports, 2026. 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
Overdoses in the United States are increasingly driven by co-occurring stimulant and fentanyl use, yet limited research has examined individual-level stimulant use patterns over time. We assessed self-reported stimulant use among 505 people who use drugs enrolled in the Rhode Island Prescription and Illicit Drug Study (RAPIDS) from 2020 to 2024. Group-based trajectory modeling identified distinct patterns of past-month stimulant use over 12 months of follow-up. We examined associations between trajectories and sociodemographic characteristics, other substance use patterns, and mental health diagnoses. Four distinct stimulant use trajectories emerged: low (12%), low/moderate (52%), moderate/high (19%), and high (17%) use. The high-use group exhibited the highest proportion of people who were unhoused (82%,
