Association of inferior vena cava diameter, functional disability, and dehydration with clinical outcomes in elderly patients.
Article in Irish journal of medical science, 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
backgroundDehydration is a common yet frequently underestimated condition in elderly patients and is associated with increased mortality and intensive care unit (ICU) admission. Clinical assessment of volume status remains challenging in this population. This study aimed to evaluate the relationship between inferior vena cava (IVC) diameter, functional disability, dehydration, and clinical outcomes in elderly emergency department (ED) patients.
methodsThis prospective observational study enrolled patients aged ≥ 60 years presenting to a tertiary ED with non-traumatic conditions between April 2023 and December 2024. IVC diameter was measured ultrasonographically at baseline (IVC
resultsAmong 212 elderly patients, 69.3% had a fluid deficit. Overall, 57.5% were hospitalized, 43.8% required ICU care, and in-hospital mortality occurred in 21.7%. Patients with fluid deficit demonstrated significantly lower IVC
conclusionDehydration is prevalent among elderly ED patients and strongly associated with adverse outcomes. Point-of-care IVC ultrasonography combined with functional assessment enables rapid identification of high-risk patients. Lower IVC
