Factors Related to Early Versus Late Hospital Arrival in Acute Ischemic Stroke
Bibliographic record
Abstract
Background: The onset-to-arrival time affects the decision of intravenous thrombolysis therapy which is associated with stroke’s prognosis. This study aimed to evaluate factor associated with early and late arrival of patients with Acute Ischemic Stroke and the effect on patients’ outcomes. Materials and Methods: Patients confirmed with acute ischemic stroke in central stroke centers were included in a prospective study. The patients were grouped into early arrivers (less than 4.5 hours) and late arrivers (at and after 4.5 hours). Patients’ data were obtained from the stroke registry system. Results: In Summary, Higher initial NIHSS, less than 15 km from the hospital, a history of CVA, Diabetes, Abnormal blood pressure, EMS transportation, Atrial fibrillation, and current use of anticoagulants, Not using opium, and not smoking was significantly associated with early arrival time. Normal blood pressure AF was a negative and significant (p-value=0.001, Odds ratio: 0.38) predictor of the late arrival. Normal blood pressure was a positive and significant (p-value<0.001, Odds ratio: 4.762) predictor of the late arrival. Conclusion: Some baseline factors are associated with the onset-arrival time of patients with ischemic stroke.

How this classification was reachedexpand
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.
