Emergency department attendance stratified by cause and frailty status: A national retrospective cohort study.
Article in Geriatrics & gerontology international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
aimThe aim of this study was to determine whether the causes of emergency department (ED) attendance and clinical outcomes vary by frailty status.
methodsUsing the Nationwide ED Sample, causes of attendance were stratified by Hospital Frailty Risk Score (HFRS). Logistic regression was used to determine adjusted odds ratios (aORs) and 95% confidence intervals (95% CIs) of ED and overall mortality.
resultsA total of 155 497 048 ED attendances were included, of which 125 809 960 (80.9%) had a low HFRS (<5), 27 205 257 (17.5%) had an intermediate HFRS (5-15), and 2 481 831 (1.6%) had a high HFRS (>15). The most common cause of ED attendance in the high-HFRS group was infectious diseases (43.0%), followed by cardiovascular diseases (CVD) (24.0%) and respiratory diseases (10.2%). For the low-HFRS group, musculoskeletal disease was the most common cause (21.2%), followed by respiratory diseases (20.6%) and gastrointestinal diseases (18.5%). On adjusted analysis, high-HFRS attendances had increased overall mortality (combined ED and in-hospital) across most attendance causes, compared with their low-risk counterparts (P < 0.001). High-HFRS attendances with infectious diseases, CVD, and respiratory diseases had an increased risk of overall mortality, compared with their low-risk counterparts (aOR 23.88, 95% CI 23.42-24.34 for the infectious disease cohort; aOR 2.58, 95% CI 2.55-2.61 for the CVD cohort; and aOR 36.90, 95% CI 36.18-37.62 for the respiratory disease cohort).
conclusionsFrailty is present in a significant proportion of ED attendances, with the cause varying by frailty status. Frailty is associated with decreased ED and increased overall mortality across most attendance causes. Geriatr Gerontol Int 2025; 25: 1350-1358.
