Abstract
Since the efficacy of endovascular therapy (EVT) for ischemic stroke was established in 2015, its indications expanded considerably. The treatment time window has been extended from 6 to 24 hours from last seen well, and patients with large infarct cores and/or low Alberta Stroke Program Early CT Scores also demonstrated treatment benefit, contrary to initial expectations. In addition, patients with basilar artery occlusions - not included in the initial EVT trials - seemed to benefit from EVT as well. However, controversy persists regarding the treatment effect for patients with more distal or so-called medium vessel occlusions or with mild neurologic symptoms (defined as a National Institutes of Health Stroke Scale [NIHSS] score ≤5). For these patients, the smaller clinical improvements to be gained should be carefully weighed against the inherent potential risks of invasive treatments such as EVT. Although several randomized trials investigated treatment effects in patients with medium vessel occlusions, less attention has been paid to treatment of patients with low baseline NIHSS scores, particularly in the late window.

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.
