Impact of COVID-19 on emergency department visits for individuals with psychotic disorders in Newfoundland and Labrador, Canada: A longitudinal study.
Article in PLOS global public health, 2025. 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
During the global COVID-19 pandemic, emergency departments (EDs) saw an overall decrease in utilization. However, some vulnerable groups, such as those living with psychotic disorders, must often rely on the services provided by EDs. The literature in this area lacks methodologically robust longitudinal studies which examine the ED utilization patterns of individuals with psychotic disorders both before and during the pandemic. This research was a longitudinal retrospective cohort study of individuals with a psychotic disorder in Newfoundland and Labrador before COVID-19 (2011-2019) and during the pandemic (2020-2022). Patients diagnosed with a psychotic disorder between April 1st, 2011, and March 31st, 2022, who were between 15-24 years old, and who visited an ED at least once, were included. Average monthly visits were used to measure ED visits to control for differences in each individual's data. Independent variables in the analyses were: 1) age, 2) sex, 3) geographic region, 4) urban or rural residence, and 5) ED visit before or during COVID-19. Multiple linear regression with Generalized Estimating Equations (GEE) modelling was used to identify factors associated with mean monthly ED visits. Multivariate analysis showed the mean monthly ED visits increased significantly during the first year of COVID-19 than before the pandemic (Mean = 0.30 vs Mean = 0.21, p = 0.01). Female individuals and rural residents also had significantly higher mean monthly ED visits than male individuals (Female = 0.51 vs Male = 0.21, p < 0.01) and urban residents (rural = 0.38 vs urban = 0.21, p = 0.02). ED utilization by individuals with psychotic disorders increased during the first year of the COVID-19 pandemic, while ED use by most Canadians decreased. This study identified the demographics of Canadians who require extra support during a health crisis. There is always the possibility of another global pandemic, and the Canadian healthcare system must be equipped to provide adequate services to all Canadians, especially those who are most marginalized.
