1 · What the graph read from it

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.

2 · The registry

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

Objective: To examine risks of severe adverse patient outcomes shortly after a left-without-being-seen emergency department (LWBS ED) visit since 2020. Methods: In this retrospective study using linked administrative data, we examined temporal trends in monthly rates of ED and LWBS visits for adults in Ontario, Canada, 2014‒2023. In patient-level analyses restricted to the first eligible LWBS ED visit, we used modified Poisson regression to compare the composite outcome of 7-day all-cause mortality or hospitalization following a LWBS ED visit for April 1, 2022‒March 31, 2023 (recent period) to April 1, 2014‒March 31, 2020 (baseline period), adjusted for age, sex, and Charlson comorbidity index. Results: Despite fewer monthly ED visits since 2020, temporal trends revealed sustained increases in monthly LWBS rates. LWBS ED visits after April 1, 2020 exceeded the baseline period's single-month LWBS maximum of 4.0% in 15 out of 36 months. The composite outcome of 7-day all-cause mortality or hospitalization was 3.4% in the recent period versus 2.9% in the baseline period (adjusted risk ratio [aRR] 1.14, 95% confidence interval [CI] 1.11‒1.18) and remained elevated at 30 days (6.2% vs. 5.8%, respectively; aRR 1.05, 95% CI 1.03‒1.07), despite similar rates of post-ED outpatient visits (7-day recent and baseline: 38.9% and 39.7%, respectively, Conclusions: The rate of short-term mortality or hospitalization after a LWBS ED visit has recently increased, despite fewer ED visits/month and similar proportion of post-ED outpatient encounters. This concerning signal should prompt interventions to address system- and population-level causes.
