Risk Factors and Prognostic Models in Acute Large Vessel Occlusion Stroke: Insights From ASPECTS-Net Water Uptake.
Article in Brain and behavior, 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
backgroundThe outcomes of endovascular reperfusion in acute large vessel occlusion stroke (ALVOS) vary, with some patients recovering fully while others face disability or mortality despite recanalization. Alberta stroke program early CT score-net water uptake (ASPECTS-NWU), a quantitative imaging metric assessing tissue edema and infarct progression, may improve prognostic accuracy.
methodsThis study included 96 ALVOS patients between December 2020 and March 2024. Patients were categorized into good (modified Rankin Scale [mRS] 0-2) and poor (mRS 3-6) prognosis groups based on 90-day mRS outcomes. Feature selection using Least Absolute Shrinkage and Selection Operator (LASSO), Boruta, and logistic regression (LR) identified key predictors, including LVO, Alberta Stroke Program Early CT Score (ASPECTS), ASPECTS from the follow-up CT (ASPECTSFCT), and National Institutes of Health Stroke Scale (NIHSS) scores. Predictive performance was validated with cross-validation, and model calibration was assessed via calibration curves, receiver operating characteristic (ROC) curves, area under the curve (AUC), and the Spiegelhalter Z-test (significance set at p < 0.05).
resultsLR highlighted LVO, ASPECTS, ASPECTSFCT, and NIHSS as significant predictors of poor prognosis. The constructed nomogram enables individualized risk assessment, with total points correlating to poor outcome probability. ROC analysis showed good discriminatory ability in the training set (AUC 0.815, 95% confidence interval [CI]: 0.714-0.916) but moderate performance in the test set (AUC 0.688, 95% CI: 0.484-0.891). Calibration was strong in the training set (Spiegelhalter Z < 0.0001) but showed minor issues in the test set (Spiegelhalter Z = 1.222).
conclusionsThis study highlights the prognostic value of ASPECTS-NWU in ALVOS and its integration into a predictive nomogram for individualized risk assessment. By refining ischemic injury stratification, ASPECTS-NWU can guide therapeutic decisions, optimize post-reperfusion management, and improve patient outcomes.
