Association of Net Water Uptake With Catastrophic Functional Outcome After Thrombectomy in Patients With Large Infarcts
Bibliographic record
Abstract
BACKGROUND: This study aimed to investigate whether net water uptake (NWU) is associated with 3-month catastrophic functional outcome (modified Rankin Scale score, 5-6) and to develop predictive models with preprocedural factors, including NWU, in patients with large infarcts who underwent endovascular thrombectomy. METHODS: This multicenter observational cohort study conducted in Korea included patients with anterior circulation stroke and an Alberta Stroke Program Early Computed Tomography Score (ASPECTS) of ≤5 receiving endovascular thrombectomy between 2015 and 2023. NWU, a quantitative imaging biomarker reflecting the degree of hypoattenuation on noncontrast computed tomography, was measured across the entire ASPECTS region (ASPECTS10-NWU), and its association with catastrophic functional outcome was assessed using a mixed-effects logistic regression model, adjusting for age, sex, prestroke modified Rankin Scale score, baseline National Institutes of Health Stroke Scale score, baseline ASPECTS, onset-to-baseline noncontrast computed tomography time, and intravenous tissue-type plasminogen activator, with hospital included as a random effect. Moreover, a predictive model has been developed with preprocedural factors that were significant covariates from the mixed-effects logistic regression analysis. RESULTS: <0.001). The model integrating ASPECTS10-NWU with preprocedural variables suggested predicted catastrophic functional outcome probabilities; as ASPECTS10-NWU and baseline National Institutes of Health Stroke Scale score increased, the marginal probability of catastrophic functional outcome increased in all age (<80 and ≥80 years) and prestroke modified Rankin Scale score (0-1 and 2-4) groups, with the patients aged ≥80 years and with prestroke modified Rankin Scale score of 2 to 4 having higher outcome probability. CONCLUSIONS: Elevated ASPECTS10-NWU is strongly associated with catastrophic functional outcome in patients with large infarcts treated with endovascular thrombectomy. Integrating the ASPECTS10-NWU with clinical variables may provide patient-specific prognostication that may assist clinicians in decision-making for endovascular thrombectomy in large infarcts.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
