Abstract

fetched live from OpenAlex

Background: Accumulating evidence from randomized-controlled clinical trials (RCTs) suggest that tenecteplase may represent an effective treatment alternative to alteplase for acute ischemic stroke (AIS). In the present systematic review and meta-analysis we sought to compare the efficacy and safety outcomes of intravenous tenecteplase to intravenous alteplase administration for AIS patients with large vessel occlusions (LVO). Methods: We searched MEDLINE and Scopus for published RCTs providing outcomes of AIS with confirmed LVO receiving intravenous thrombolysis with either tenecteplase at different doses or alteplase at standard dose 0.9mg/kg. The primary outcome was the odds of modified Rankin Scale (mRS) score of 0-2 at 3 months. Results: We included 4 RCTs including a total of 433 patients. Patients with confirmed LVO receiving tenecteplase had higher odds of successful recanalization (OR=3.05, 95%CI: 1.73-5.40; Figure A), mRS scores of 0-2 [odds ratio (OR)=2.06, 95%CI: 1.15-3.69; Figure B], and functional improvement defined as 1-point decrease across all mRS grades (common OR=1.84, 95%CI: 1.18-2.87; Figure C) at 3 months compared to patients with confirmed LVO receiving alteplase. There was little or no heterogeneity between the results provided from included studies regarding the aforementioned outcomes (I 2 ≤20%). No difference in the outcomes of early neurological improvement, symptomatic intracranial hemorrhage (ICH), any ICH and the rates of mRS 0-1 or all-cause mortality at 3 months were detected between patients with LVO receiving intravenous thrombolysis with either tenecteplase or alteplase. Conclusion: AIS patients with LVO receiving intravenous thrombolysis with tenecteplase have significantly better recanalization and clinical outcomes compared to patients receiving intravenous alteplase.

Not 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.
