Impact of the LCBO strike on Ontario emergency department visits with an alcohol-related chief complaint: a natural experiment in alcohol policy.

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: Alcohol is a leading preventable cause of death and disability in Canada. Alcohol-related emergency department (ED) visits place a substantial burden on the health system, with evidence that greater alcohol availability contributes to higher utilization and related harms. The July 2024 Liquor Control Board of Ontario (LCBO) strike provided a natural experiment to evaluate the impact of reduced alcohol availability on healthcare utilization. Methods: An interrupted time series analysis was conducted to evaluate ED visits with an alcohol-related chief complaint, as captured in the Acute Care Enhanced Surveillance System for Ontario, across three time periods: before, during, and after the LCBO strike. Run charts were utilized to compare visit patterns with historical trends. Poisson regression models, both unadjusted and adjusted for weekly temporal patterns, were used to assess changes in visit rates. Results: ED visits with an alcohol-related chief complaint decreased by 24% during the LCBO closure (aRR: 0.76, 95% CI 0.66-0.88) and declined over the strike period (aRR: 0.98, 95% CI 0.97 - 1.00). They increased by 32% when LCBOs reopened (aRR: 1.32, 95% CI 1.02 - 1.70). Comparing 2024 7-day moving averages with 2023 values (± 1SD and ± 2SD) demonstrated that ED visits during the 2024 closure were significantly lower than in 2023. Interpretation: Reduced alcohol availability during the LCBO strike was associated with a significant decline in ED visits with an alcohol-related complaint, underscoring the potential health system benefits of reducing alcohol availability. The findings may inform policymakers considering measures to reduce alcohol-related healthcare burdens.
