Intensive Care Unit Room Characteristics and Association with the Development of Delirium.
Article in NeuroSci, 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
introductionDelirium is associated with worse outcomes in critically ill patients. Factors that could reduce delirium are patients' environment and maintaining circadian cycles, but whether certain room characteristics improve the incidence of delirium is unclear. Our objective was to investigate whether the presence of windows or doors in patients' rooms is associated with lower rates of delirium.
methodsIn this retrospective, cohort study, adult, medical patients admitted to the Intensive Care Unit (ICU) between 1 January 2024 and 1 July 2024 were identified. Clinical and room characteristics were collected. The primary outcome was the development of Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) positive status. Secondary outcomes included ICU and hospital length of stay (LOS) and mortality.
resultsFour hundred fifty-eight (458) patients met inclusion criteria (mean age 61.7 +/- 16.4 years; 51.3% male). In the adjusted multivariate analysis, neither the presence of windows (aOR 2.2; 95% CI 0.7-6.2;
conclusionRoom characteristics were not significantly associated with delirium or secondary outcomes after FDR correction. However, given the study's limited power to detect moderate differences, these findings do not definitively rule out an architectural influence on delirium and warrant further investigation in larger cohorts. Studies with more discrete measurement of room characteristics are needed to investigate these associations further.
