Serial aEEG reached an AUC of 0.886, but prognosis remains unvalidated

In 156 selected infants born before 28 weeks, major brain injury was associated with a 1.45-point lower Burdjalov score at 32 weeks, and the retrospective within-cohort AUC was 0.886. But 118 of 274 screened infants were excluded, the reference group was mostly grade II IVH, and no long-term outcome was measured. This is group separation, not a bedside prognosis.

THE HOT TAKE

An AUC can describe separation inside a dataset. It does not automatically forecast an infant's future.

A 2026 single-center retrospective cohort analyzed 723 serial aEEG recordings from 156 infants born before 28 weeks. At 32 weeks PMA, infants with imaging-defined major brain injury had Burdjalov maturation scores 1.45 points lower than the reference group (95% CI 1.25 to 1.65 points lower). The largest retrospective within-cohort AUC was 0.886, but the study did not test future diagnosis, clinical decisions, or long-term development.
