Abstract
Objective: Timely and effective recanalization of the occluded vessel is of importance for acute ischemic stroke patients. However, Successful recanalization (SR) is not always associated with good prognosis. We aimed to explore predictive factors of poor outcome of successful recanalization after thrombectomy in patients with acute anterior circulation large-vessel occlusion.Method: Between January 2016 and October 2018, the eligible patients with SR were retrospectively enrolled. Poor outcome was defined as modified Rankin Scale (mRS) of 3 to 6 at 90 days. We used univariate and multivariate logistic regression analysis to explore risk factors of poor outcome.Results: We enrolled 76 patients with SR (mean age: 64.34 u00b1 14.90, 46 males). The proportion of patients with poor outcome was 57.9% (44/76). The multivariable logistic regression showed systolic blood pressure (SBP) (OR, 1.03; 95% CI, 1.00-1.07; P=0.041), baseline National Institutes of Health Stroke Scale (NIHSS) score (OR, 1.17; 95% CI, 1.04-1.31; P=0.007 ), and blood glucose levels (OR, 1.80; 95% CI, 1.09u20132.96; P=0.022 ) were the predictive factors of poor outcome, while baseline Alberta Stroke Program Early CT Score (ASPECTS) was the protective factor. (OR, 0.49; 95% CI, 0.33u20130.73; P<0.001). Conclusion: High SBP, high NIHSS, high blood glucose and low ASPECTS were associated with poor outcome despite successful recanalization after thrombectomy in patients with acute ischemic stroke. Further large sample studies are needed.

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 it
