"Geriatric patients in Argentinean ICUs: admission, care patterns, outcomes and healthcare system implications".
Observational study in BMC geriatrics, 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
backgroundArgentina is one of the countries with a higher elderly population in South America and up to now, there is a lack of local data describing the characteristics and outcomes of this population admitted to intensive care units. Our study aims to determine the prevalence of elderly patients admitted to the ICU and describe their characteristics, outcomes and implications in healthcare system.
methodsThis is an observational, retrospective study analyzing data from the Argentine Critical Care Society (SATI-Q) database between 2011 and 2019. Elderly patients were defined as those aged 75 years or older, and very elderly patients as those aged 90 years or older. The primary outcome was in-hospital mortality. Secondary outcomes included ICU length of stay, complications, and device-associated infection rates.
resultsBetween 2011 and 2019, 28,625 (19.8%) patients aged 75-90 years and 2,037 (1.4%) patients above 90 years were included in the database; During this period, the percentage of elderly patients increased from 15.7 to 21.9%, while the proportion of very elderly rose from 1.3 to 2.2% (p = 0.0001). ICU mortality was 24% in elderly patients and 27% in very elderly patients. Secondary outcomes included a median ICU stay of 3 days, comparable complication rates, and no significant differences in device-associated infections. Multivariate analysis identified age, APACHE II score, TISS 28 score, use of MV, medical or trauma-related admission, and public healthcare as independent mortality predictors.
conclusionsStudies show rising elderly ICU admissions, with greater life support use and longer stays. This study in Argentina highlights similar trends, stressing the need to adapt public health strategies and optimize resources for more equitable care.
