We analyzed within a national prospective cohort on whether patients with minor stroke can benefit from intravenous alteplase.Methods: This observational study included patients with acute ischemic stroke with a National Institutes of Health Stroke Scale (NIHSS) score 0 to 5 at admission. The short-term outcomes at discharge and 3-month were analyzed including the modified Rankin Scale score, gait speed, Montreal Cognitive Assessment, Patient Health Questionnaire-9, General Anxiety Disorder-7 and Stroke Impact Scale-16. Multivariate regression models were performed to evaluate the association between intravenous thrombolysis and clinical outcomes.Results: A total of 1876 consecutive patients were included in the current analyses with 102 patients (5.4%) received alteplase and 1774 patients (94.5%) were in non-alteplase group. We found that 10.9% patients presented unfavorable functional outcome with a mRS ≥ 2 at 3-month. Patients with alteplase treatment had a more favorable outcome in SIS-16 at discharge (OR, 5.45; 95% CI, 2.22– 8.68) and 3-month after stroke (OR, 2.34; 95% CI, 0.17– 4.50). There was an association of alteplase with better gait speed in the restricted sample of age > 60 (OR,0.14; 95% CI, 0.02– 0.25), while an unfavorable effect was found in anxiety (OR, 2.23; 95% CI, 2.23, 0.91– 3.55) and depression (OR, 1.54; 95% CI, 0.17– 2.91) in female.Conclusion: Alteplase showed a suggestive benefit in function and motor outcomes in patients with low NIHSS score of 0– 5. Meanwhile, female seemed more inclined to post-stroke emotional problems after alteplase treatment, which should be further explored in the future.Keywords: alteplase, minor stroke, ischemic, outcomes

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
