Abstract
BACKGROUND: A prospective observational study was aimed at assessing the role of blood pressure (BP) during the first 24 h from stroke onset on the outcome of acute ischaemic stroke. METHODS: Subjects admitted within the first 3 h from stroke onset were included. Stroke severity was evaluated with the Canadian Stroke Scale (CSS). Functional recovery was defined as a modified Rankin Scale score < or =2. RESULTS: One hundred subjects were included. In a logistic regression model, the independent predictors of poor functional recovery at discharge were: age (OR = 1.12; 95% CI 1.04-1.21; p = 0.0033), non-lacunar stroke subtype (OR = 4.31; 95% CI 1.07-17.31; p = 0.0395), diabetes mellitus (OR = 8.38; 95% CI 1.67-41.95; p = 0.0097), a CSS score at admission < or =8 (OR = 28.64; 95% CI 5.59-146.68; p<0.0001), an average systolic BP during the first 6 h > or =180 mmHg (OR = 13.34; 95% CI 1.34-133.10; p = 0.0272) and a lower diastolic BP average from 6 to 24 h (OR for 5 mmHg increase: 0.57; CI 95% 0.36-0.88; p = 0.0115). Similar results were observed after 3 months of follow-up. CONCLUSION: In ischaemic stroke patients, systolic BP over 180 mmHg in the first 6 h and a decrease of diastolic BP during the 6-24 h from stroke onset were independent predictors of a poor functional recovery.

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
