Prone positioning and bleeding risk during extracorporeal membrane oxygenation in severe ARDS patients.
Observational study in Perfusion, 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
PurposeTo assess whether prone positioning (PP) increases bleeding risk compared to supine positioning in ARDS patients undergoing veno venous Extracorporeal Membrane Oxygenation (VV ECMO).Materials and MethodsA single-center retrospective observational study was conducted between January 2012 and March 2023. Data were systematically collected from an institutional ECMO registry, including baseline characteristics, daily variables, bleeding events, and outcomes. We compared the relative risk (RR) and incidence rate ratio (IRR) of bleeding between 'Prone' and 'Supine' patients. Bleeding-free days were analyzed using Kaplan-Meier curves and the Log-Rank test.ResultsWe included 136 consecutive severe ARDS patients undergoing VV ECMO (65% male, age 52 ± 11, 53% bacterial pneumonia), with 85 (62%) and 51 (38%) in the 'Prone' and 'Supine' group respectively. Bleeding occurred in 79 (58%) patients, with 43 of these being major bleeding events, including 14 intracranial hemorrhages. Fifty-two (61%) 'Prone' patients versus 27 (53%) 'Supine' patients had bleeding (RR 1.11 (95% CI: 0.81-1.52),
