Early Somatosensory Evoked Potentials in Preterm Infants: Their Prognostic Utility
Bibliographic record
Abstract
We hypothesized that somatosensory evoked potentials (SEPs) recorded early in the course of a preterm infant life would be predictive of long-term neurodevelopmental outcome. We recorded unilateral, median nerve SEPs in 88 preterm infants twice in the first 3 weeks of life (SEP1 and SEP2). We found both SEP1 and SEP2 to be significantly associated with the presence of periventricular leukomalacia on head ultrasound (p = 0.04 and p = 0.02 for SEP1 and SEP2, respectively). Both SEP1 and SEP2 were predictive of later cerebral palsy (CP) (p = 0.03 and p = 0.003, respectively). False-positive results were frequent (13 of 17 for SEP1 and 20 of 28 for SEP2). A normal SEP, even when there was periventricular echogenicity on head ultrasound, was associated with a normal outcome in all but 1 instance. SEP1 and SEP2 were less accurate than head ultrasound findings of periventricular leukomalacia in the prediction of later CP (73, 69 and 93%, respectively). SEPs done in the first 3 weeks of life may provide additional prognostic information, particularly when the test is normal. Abnormal SEPs in this period must be interpreted cautiously.

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.
