Plain Language Summary Publication: The 2023 protocol for update to acute treatment of adults with migraine in the emergency department: The American headache society evidence assessment of parenteral pharmacotherapies
Bibliographic record
Abstract
Main finding: Since the last guideline that was issued in 2016, we have found new studies about treating severe migraine attacks in the emergency room. This summary outlines our plan to review these studies and update the previous guidelines. Motivation: The American Headache Society Guideline Committee updates its guidelines as needed. Although the 2016 guideline was well done, new information is available that might change our recommendations. Methods: We will conduct an updated review using the same methods as the 2016 guideline. We will search Medline, Embase, Cochrane, clinicaltrials.gov, and the WHO International Clinical Trial Registry Platform. We will include studies on adults with migraine treated with injectable medications. Two authors will review each study's title and abstract, followed by the full text. If there is a disagreement, a third author will decide. We will assess the studies for bias using a standard tool. For some studies, we will perform a meta-analysis. We will categorize medications as "highly likely," "likely," or "possibly" effective or ineffective. The results will include a discussion of medications' risks. Results: Our goal is to provide guidance on which injectable treatments, including nerve blocks and sphenopalatine ganglion blocks, work best for adults with migraine in the emergency room. Implications: This summary outlines our plan to use an updated review and analysis to create new guidelines for the treatment of adults with migraine in the emergency room.

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.
