Risk factors for bleeding and thrombotic complications during extracorporeal membrane oxygenation support in adults based on the MIMIC-IV database.
Article in American journal of translational research, 2025. 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
objectiveTo identify risk factors for bleeding and thrombotic complications during extracorporeal membrane oxygenation (ECMO) support in adults and to develop a predictive model based on these factors.
methodData from 323 adult patients treated with ECMO in the Medical Information Mart for Intensive Care IV (MIMIC-IV) database were retrospectively analyzed. Demographic information, clinical characteristics, and laboratory test results were collected. Kaplan-Meier (K-M) and Cox regression analyses were used to identify risk factors for bleeding and thrombotic complications and construct a predictive model.
resultsBleeding and thrombotic complications was noted in 84 (26.0%) patients, with a median onset time of 13 days after ECMO. Univariate analysis identified age, Acute Physiology and Chronic Health Evaluation II (APACHE II) score, ECMO indication, ECMO withdrawal, extracorporeal cardiopulmonary resuscitation (ECPR), and coagulation function as potential risk factors (all P < 0.05). Multivariate analysis revealed that ECMO withdrawal and platelet count (PLT) were independent protective factors, while D-dimer was an independent risk factor (P < 0.05). A predictive model was developed based on ECMO withdrawal, D-dimer, and PLT, with areas under the curves (AUCs) of 0.932, 0.931, and 0.941 for predicting bleeding complications at 6, 9, and 12 days after ECMO treatment, respectively.
conclusionThe incidence of ECMO-related bleeding and thrombotic complications is high. ECMO withdrawal, PLT, and D-dimer are independent influencing factors. This predictive model can assist in early identification of high-risk patients and guide clinical decision-making.
