'Wondering and waiting’ after obstetrical brachial plexus injury: Are we underestimating the effects of the traumatic experience on the families?
Bibliographic record
Abstract
O bstetrical brachial plexus injury (OBPI) results from lateral torsion to the neck or direct traction to the upper extremity during birth. Approximately 1.6 to 2.9 per 1000 infants sustain an OBPI (1), with risk factors including birth weight >4000 g, shoulder dystocia, multiparity, prolonged labour, assisted delivery, maternal diabetes and breech presentation (2,3). The Narakas system classifies OBPI according to nerve injury severity, from least severe Narakas level I (C5-C6 lesion) to most severe Narakas level IV (C5-T1 lesion with Horner's sign) (4).
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.
How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
