Frailty and outcomes after extracorporeal membrane oxygenation: a binational registry-based cohort study.
Article in Critical care (London, England), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundFrailty predicts adverse outcomes in critical illness, but its prognostic value in patients receiving extracorporeal membrane oxygenation (ECMO) remains unclear.
methodsIn this retrospective cohort study across 116 intensive care units (ICUs), we analysed data from the Australia and New Zealand Intensive Care Society Adult Patient Database on adults (≥ 16 years) who received ECMO between 2018 and 2024. Frailty was assessed using the Clinical Frailty Scale (CFS), and we defined patients as being frail if they had a CFS of ≥ 5. The primary outcome was one-year mortality, which we assessed using g-computation. We further analysed the association between frailty and death among several subgroups, including age, sex, and primary ICU admission diagnostic group (cardiac medical, cardiac surgical, cardiac arrest, respiratory, transplant, and others). Secondary outcomes included in-hospital and ICU mortality, lengths of hospital and ICU stay, delirium, and pressure injuries.
resultsWe included 2,084 patients (51.3 years [IQR: 38.9–61.3], 64.2% male). Frailty was present in 254 (12.2%) patients. The adjusted one-year mortality was 41.9% (760/1830) in patients without frailty and 42.1% (113/254) in patients with frailty (adjusted risk difference: +0.27%, 95%-CI: -6.65% to +7.19%). These results were consistent across sensitivity and subgroup analyses, particularly amongst principal diagnostic groups (cardiac medical: -7.87%, cardiac surgical: + 3.70%, cardiac arrest: -1.66%, respiratory: + 10.02%, transplant: + 2.19%, others: -0.58%).
conclusionsFrailty was not associated with short or long-term mortality among patients who received ECMO. This may reflect patterns in patient eligibility for ECMO. More studies are required to investigate this relationship and validate these findings.
