Amphetamine-Related Emergency Department Visits in Ontario, Canada, 2003-2020.
Article in Canadian journal of psychiatry. Revue canadienne de psychiatrie, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
objectivesDespite unregulated amphetamine use increasing, there are limited data on related emergency department (ED) visits in Canada. Our primary objective was to examine trends in amphetamine-related ED visits over time in Ontario, including by age and sex. Secondary objectives were to examine whether patient characteristics were associated with ED revisit within 6 months.
methodsUsing administrative claims and census data, we calculated annual patient- and encounter-based rates of amphetamine-related ED visits from 2003 to 2020 among individuals 18+ years of age. We also performed a retrospective cohort study of individuals with amphetamine-related ED visits between 2019 and 2020 to determine whether select factors were associated with ED revisit within 6 months. Multivariable logistic regression modelling was used to measure associations.
resultsThe population-based rate of amphetamine-related ED visits increased nearly 15-fold between 2003 (1.9/100,000 Ontarians) and 2020 (27.9/100,000 Ontarians). Seventy-five percent of individuals returned to the ED for any reason within 6 months. Psychosis and use of other substances were both independently associated with ED revisit for any reason within 6 months (psychosis: AOR = 1.54, 95% CI = 1.30-1.83; other substances: AOR = 1.84, 95% CI = 1.57-2.15), whereas having a primary care physician was negatively associated with ED revisit (AOR = 0.77, 95% CI = 0.60-0.98).
conclusionsIncreasing rates of amphetamine-related ED visits in Ontario are cause for concern. Diagnoses of psychosis and the use of other substances may serve to identify individuals who are most likely to benefit from both primary and substance-specific care.
