Sex differences in the 1-year outcomes of emergency department patients with alcohol withdrawal.
Article in CJEM, 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
backgroundAlcohol withdrawal is a common emergency department (ED) presentation, but differences in long-term outcomes between female and male patients are not clear.
methodsFrom January 1, 2015, to December 31, 2018, at three urban EDs in Vancouver, British Columbia, we studied patients who were discharged with a primary or secondary diagnosis of alcohol withdrawal. We performed a structured chart review to ascertain patient characteristics and ED treatments. We linked with regional ED and provincial data to obtain the outcomes of 1-year return ED visits and mortality, respectively. The primary outcome was at least one return visit to the ED, and secondary outcomes included ED revisits and 1-week, 1-month, and 1-year mortality. We compared female patients with male patients using descriptive methods.
resultsWe identified 1,019 unique patients with 273 (26.8%) female. Median ages, ambulance arrival, initial withdrawal severity score, and index visit admission rates were similar. At 1 year, 186 (68.1%) female and 515 (69.0%) male patients reattended an ED, for a difference of 0.9%; (95% CI - 5.5 to 7.7%). A significantly greater proportion of male patients reattended at 1 week and 1 month, and the average number of male ED revisits was greater at 1 week, 1 month, and 1 year. By 1 year, a female patient (0.4%) and 19 males (2.6%) died, for a difference of 2.2% (95% CI 0.3-3.6%).
conclusionDespite similar ED presentations, female patients with alcohol withdrawal had fewer 1-year ED visits and lower mortality. EDs may wish to incorporate sex-specific approaches to post-discharge management.
