Randomized controlled trials in emergency settings: Taking a HEADSTART on acute type A aortic dissection trials
Bibliographic record
Abstract
Emergency operations comprise up to 50% of the surgical practice across specialties, yet only 9.4% of surgical trials are related to emergency surgery settings.1 In vascular surgery, nascent experiences arose from the IMPROVE trial (Immediate Management of Patients with Rupture: Open Versus Endovascular Repair) for ruptured abdominal aortic aneurysms (AAA), randomizing patients to either open or endovascular surgical repair. In emergency thoracic aortic surgery, the Dissected Aorta Repair Through Stent Implantation (DARTS) and ARISE trials provided non-randomized insights, but no randomized trials have been conducted in the acute setting to date.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
