Propofol Use and Delirium in Patients Aged 80 Years and Over: A Retrospective Cohort Study of 9850 ICU Admissions.

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
objectivesThere is inconsistent evidence regarding the relationship between propofol and delirium, and this evidence is predominantly drawn from mixed-age adult cohorts. In this study, we examined the link between propofol exposure and the onset of delirium in patients aged 80 years and over-a rapidly growing and physiologically distinct intensive care unit (ICU) patient group.
designWe conducted a retrospective analysis of older adults (aged 80 years or over) included in the Medical Information Mart for Intensive Care (MIMIC-IV) database. We used multivariate logistic regression to examine the relationship between propofol use and the occurrence of delirium. To strengthen the reliability of our results, we performed sensitivity analyses using propensity score matching and inverse probability of treatment weighting, as well as subgroup analyses.
resultsAmong 9850 ICU patients aged > 80 years, delirium was observed in 3474 cases (35.3%). Propofol showed an independent association with delirium after covariate adjustment (OR 1.22, 95% CI 1.09-1.38). This significant link was confirmed by sensitivity analyses using inverse probability of treatment weighting (OR 1.22; 95% CI 1.09-1.38) and propensity score matching (OR 1.24; 95% CI 1.08-1.43). This finding remained consistent across most of the subgroup analyses.
conclusionsThese findings highlight the importance of careful sedation planning and increased monitoring when administering propofol to critically ill adults aged 80 years and over, who may be particularly susceptible to its neurocognitive effects.
