Delirium severity in critical patients with COVID-19 from an Infectious Disease Intensive Care Unit.
Article in International journal of infectious diseases : IJID : official publication of the International Society for Infectious Diseases, 2022. 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
backgroundCOVID-19 is mainly characterized by respiratory manifestations. Nevertheless, neurologic complications have been described, including delirium, which appears to be frequent, prolonged, and severe.
methodsWe conducted a retrospective analysis of demographic, clinical, and laboratory data of two cohorts: patients with COVID-19 admitted to the infectious disease intensive care unit (ID-ICU) and patients admitted to the ID-ICU with other respiratory infections in 2018-2019. Outcomes were defined as the presence, duration, and severity of delirium. Doses of antipsychotics used to control delirium were converted to equivalents and used as delirium severity. Logistics regression models were used to correlate COVID-19 with the outcomes.
resultsNinety-nine patients with COVID-19 and 40 patients without COVID-19 were included. The mean age of the COVID-19 cohort was 63 years, with a male predominance. Delirium developed in 42%, with a median duration of 3 days and an equivalent dose of olanzapine use of 10 mg/day. In univariate analysis, COVID-19 was not associated with the development or different duration of delirium when compared with patients without COVID-19. There was an association between COVID-19 and severity of delirium in a binary logistic regression model controlled to confounding variables.
conclusionCOVID-19 is not associated with a higher prevalence or duration of delirium than in cohorts without COVID-19. However, it is associated with more severe forms of delirium.
