Socioeconomic status and ECMO outcomes in severe ARDS.
Article in Annals of intensive care, 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
Background: Socioeconomic inequalities have been associated with adverse outcomes in critically ill COVID-19 patients. Whether these disparities extend to the most severe ARDS patients treated with ECMO, regardless of etiology, remains uncertain. We aimed to compare the socioeconomic profiles, management, and outcomes of COVID-19 ARDS patients on ECMO with those treated for ARDS due to other causes, using the nationwide French healthcare database. Results: From March 2015 to December 2021, 1722 adults received ECMO for acute respiratory failure: 1245 with COVID-19, 107 with influenza, and 370 with other causes. Overall, 27% lived in the most deprived neighborhoods, with consistent overrepresentation across etiologies (26.8% COVID-19, 29% influenza, 25.3% other) compared to less deprived neighborhoods (p = 0.039). In-hospital mortality was 56% in COVID-19, 48% in influenza, and 60% in other causes (p = 0.080). Median ICU stay was longest in COVID-19 survivors (56 [36-78] days), who also required longer ECMO support and experienced more complications. Independent predictors of in-hospital death included older age and need for renal replacement therapy at ECMO initiation, while socioeconomic deprivation was not associated with outcomes. After adjustment, mortality was higher in non-COVID-19, non-influenza patients compared with influenza (Odds ratio 1.70, 95% confidence interval [1.03-2.81]). Conclusions: Severe ARDS requiring ECMO disproportionately affected patients from socioeconomically deprived areas, irrespective of etiology. However, deprivation was not linked to worse outcomes.
